Adds a second tab on /pricelist that shows the structured
`price_list` collection (AI-extracted line items) instead of the
raw PDF uploads. Operators can now:
- Search across SKU, description, and brand
- Filter by category (twist_drill, hss_cutter, countersink, ...)
- Filter by brand (JEI, TurboSteel, TurboTough, ...)
- See cost vs selling price side-by-side in ZAR
- Click a row's 'Source' link to jump back to the raw PDF
The distinct filter values are pulled from a one-shot getList(1, 500)
on mount, with hardcoded fallbacks (FALLBACK_CATEGORIES /
FALLBACK_BRANDS) so the dropdowns are useful even before any
extractions have run.
Layout: Tabs (Raw Uploads | Catalogue) wrap both views; the
header + page chrome stay shared. The DeleteDialog stays outside
the Tabs since it's a modal.
Also ships an idempotent migration to add `source_file` (text)
to `price_list` — used by the n8n workflow to track which raw
PDF each extracted row came from, and by the verify-after-POST
step the workflow uses to decide whether to flip
`raw_price_list.status` to Completed vs Failed.
Price type is in PriceListRow (shared subset) and PriceList
(full record). Supplier names are resolved client-side via
getAllSuppliers() since the live schema has supplier as a text
field rather than a relation.
Tests: 229/230 (same pre-existing failure, unrelated). TypeScript
clean.
