feat(quotes): add operator-facing notes functionality to quotes

- Introduced a new `quote_notes` field to store operator-facing free-text notes, distinct from the existing `notes` field used for rejection audit logs. - Updated the quote processing page to include a `QuoteNoteCard` for editing and displaying the operator notes, ensuring seamless integration into the PDF generation flow. - Enhanced the PDF generation logic to render the operator notes in a blue callout below the totals, improving visibility for end-users. - Implemented a new service function `setQuoteNotes` to handle the saving of notes, including trimming whitespace and handling non-string inputs defensively. - Added unit tests for the `setQuoteNotes` function to ensure correct behavior and data integrity when updating notes. - Updated relevant types and documentation to reflect the new functionality and its intended use cases.

+# Quote-Level Notes — Plan
+
+## Goal
+
+Let the operator attach a free-text note to a quote on the process page, saved to PocketBase, and rendered on the customer-facing PDF.
+
+## Decisions (resolved with the user)
+
+| # | Decision | Choice |
+|---|----------|--------|
+| 1 | Storage | **New PB field** `quote_notes` (text, optional). Existing `quotes.notes` is reserved for the rejection audit log written by `review-approve/route.ts:194`. |
+| 2 | PDF placement | **Below the items table, above totals** — same sibling-style as the existing `partialNote` callout at `quote-document.tsx:221-225`. Blue accent (not amber) so the two don't visually merge. |
+| 3 | Save UX | **Auto-save on blur / debounce** (~600 ms). No toast storm; small "Saved Xs ago" indicator. |
+| 4 | Edit surface | **Process page only.** Detail page (`/quotes/[id]`) is read-only. |
+
+## Schema changes (operator action required)
+
+Add a new text field to the `quotes` collection in the **PocketBase admin UI** (per `AGENTS.md` — the local `pb-exports/pb_schema-2.json` is a snapshot only, the running PB instance is the source of truth):
+
+- Name: `quote_notes`
+- Type: `text`
+- Required: **no**
+- Max length: **0** (unbounded, matching the existing `quotes.notes` shape)
+- Hidden: **no**
+
+After the field is added, update `pb-exports/pb_schema-2.json` so future deploys and the schema snapshot stay in sync.
+
+## Implementation
+
+### 1. Type — extend `Quote`
+File: `src/lib/types.ts` (around the existing `Quote` interface, line ~178).
+
+Add `quote_notes?: string` as an optional field. Document that it is separate from `notes` (which is the rejection audit log).
+
+### 2. Service — `setQuoteNotes(quoteId, notes)`
+File: `src/lib/server/quotes-service.ts` (add to the existing file; no new service file).
+
+Signature: `setQuoteNotes(quoteId: string, notes: string) => Promise<Quote>`. Trims, treats empty as `""`, calls `pb.collection("quotes").update(quoteId, { quote_notes })`, returns the updated row. Existing `quote_notes` audit (`who/when`) deferred — the field is plain operator text, not policy.
+
+### 3. REST route — `PATCH /api/v1/quotes/[id]`
+File: `src/app/api/v1/quotes/[id]/route.ts` (**new file**).
+
+Currently `/api/v1/quotes` is a GET-list only and there is no PATCH for a single quote (the MCP `quotes.update` calls PB directly). Add a `PATCH` handler:
+
+- Auth: same operator-session model as `/api/v1/quotes/[id]/items` route (admin PB on the server, no `assertAgentAuth`).
+- Body: `{ quote_notes?: string }` (whitelisted — the route only accepts fields in a small allowlist, not a free-form PATCH).
+- Calls `setQuoteNotes(id, body.quote_notes)` and returns `{ quote }`.
+- Validation: if `quote_notes` is not a string, return 400.
+
+Add a `GET` handler too (or skip — the process page already loads the quote via `getQuote`, so we don't need a GET here). Keep the file scoped to PATCH/add-only the operators need.
+
+### 4. UI — new `QuoteNoteCard` component
+File: `src/components/quotes/process-quote-note-card.tsx` (**new file**).
+
+Renders a Card with a Textarea bound to `quote.quote_notes`. Behaviour:
+
+- Local `useState` mirror of the prop. On change, debounce 600 ms then call `PATCH /api/v1/quotes/{id}` with `{ quote_notes }`. On blur, flush immediately (so the operator doesn't lose work if they navigate).
+- "Saved 3s ago" indicator (a small muted-text line under the textarea) — uses `setInterval` to update the relative timestamp. Hidden until the first save.
+- No toast on save (would be annoying during normal typing). Error states show a destructive "Failed to save — retry" hint that re-enables the input.
+- Empty placeholder text: *"Add a note for the customer. e.g. 'Valid for 30 days', 'Lead time 5 working days', 'Subject to stock availability.'"*
+- Card placed **above the "Generate Quote PDF" Card** in `process/page.tsx` (around line 1525), below the items table, above the outbound attachments card.
+
+Wire it in: `process/page.tsx` imports `QuoteNoteCard` and renders `<QuoteNoteCard quoteId={quote.id} initialNotes={quote.quote_notes ?? ""} />` after the items Card.
+
+### 5. PDF render
+File: `src/lib/pdf/quote-document.tsx`.
+
+- Extend `QuoteDocumentProps` (line ~72) with `quoteNotes?: string | null`.
+- Add a new view **between the items table totals block (line 213) and the `partialNote` view (line 221)**. Renders only when `quoteNotes` is a non-empty string. Style: blue accent (`#2D6CDF` border, `#EEF3FF` background) — same shape as the partialNote box but a different palette so the two don't visually merge.
+- Label: "Note" (plain text, fontSize 10, bold).
+
+File: `src/app/api/v1/quotes/[id]/pdf/route.ts`.
+
+- Pass `quote.quote_notes` through to the document props (around line 265 where `partialNote` is currently passed).
+
+### 6. Tests
+
+- `src/lib/server/quotes-service.test.ts` — unit test for `setQuoteNotes`: trims whitespace, rejects non-string, calls PB with the right shape, returns the updated row.
+- `src/app/api/v1/quotes/[id]/route.test.ts` (**new file**) — integration tests: 200 happy path, 400 on non-string `quote_notes`, 404 on missing quote, 500 on PB failure.
+- `src/lib/pdf/quote-document.test.tsx` (**new file** or extend existing) — render the document with `quoteNotes` set → assert the text appears below the items; render with `quoteNotes=""` → assert the box is absent.
+- `src/components/quotes/process-quote-note-card.test.tsx` (**new file**) — debounce flushes, blur flushes immediately, error path renders the retry hint.
+
+## Out of scope
+
+- The per-item `quote_items.notes` Textarea at `process/page.tsx:1442-1449` silently drops typed content (the `saveItem` callback at line 562-585 doesn't include `notes` in `persistedSnapshot`). This is a separate bug — the user explicitly asked about quote-level notes, not per-item notes. **Not fixed here.**
+- The "NOTE" magic description hack at `process/page.tsx:552` is left untouched — it's a narrow bypass for `saveItem`, not a UI feature.
+- Reject-audit migration: existing `quotes.notes` rows remain as the audit log. No backfill.
+- Quote history / timeline entry when notes change (could be added later via the existing `audit_logs` collection if the user wants a "who changed the note and when" trail).
+
+## Validation
+
+- `npm run lint`
+- `npm run typecheck`
+- `npm run test`
+- Manual: load a quote on the process page, type a note, wait 1 s, refresh the page — note should be persisted. Click Generate PDF → open the PDF and assert the note box is present.
+
+## Risks
+
+- **PB schema drift**: the plan assumes the operator adds the field. If they don't, every PATCH will return 400 from PB. The route should surface the PB error message verbatim so the operator notices.
+- **Auto-save on blur during PDF generation**: the PDF render reads the live `quote.quote_notes` from PB, so a typed-but-not-yet-flushed note won't appear on a PDF generated immediately. Mitigation: the blur-flush + the existing PDF button's focus loss will normally flush; if the operator types and clicks Generate without leaving the textarea, the PDF misses the unflushed change. Acceptable — clicking the button blurs the textarea.
+- **Concurrent edits**: two browser tabs both editing the same note. Last-write-wins, no merge. Acceptable for operator-only workflow.

+/**
+ * QuoteNoteCard — operator-facing free-text note editor on the
+ * `/quotes/[id]/process` page. The note is rendered on the customer
+ * PDF (blue callout below the totals — see `quote-document.tsx`).
+ *
+ * Storage: PocketBase `quotes.quote_notes` (text, optional). Updated
+ * via `PATCH /api/v1/quotes/[id]` with body `{ quote_notes }`. Does
+ * NOT touch the audit-log field `quotes.notes`.
+ *
+ * Save UX: debounced (~600 ms) auto-save on type, immediate flush on
+ * blur — so clicking "Generate PDF" flushes any in-flight edit before
+ * the PDF is rendered. A small "Saved Xs ago" indicator substitutes
+ * for a toast so the operator doesn't get interrupted during normal
+ * typing. Errors surface a destructive hint and re-enable the input
+ * so the next debounced attempt can retry.
+ *
+ * NOTE: this component is intentionally scoped to the process page
+ * (per the plan). The quote detail page (`/quotes/[id]`) stays
+ * read-only with respect to `quote_notes`.
