David f85b9378a2 Add Running Costs sub-pages: insurance, financing, purchases, oil, operators, mechanics
Splits the Running Costs group into six purpose-built pages, each with its own
collection and its own source data, plus a coordinate parser for purchase orders.

Insurance (R503 330/yr, 20 vehicles)
  A premium can move every month or three, so it is stored as a RATE PERIOD in
  insurance_rates and each month's cost is resolved against the rate in force
  that month. cost_lines insurance rows are derived from those periods. An absent
  rate is null, never 0 — nobody has entered the date, which is not the same as
  being insured for free.

Financing (20 agreements, R428 585/mo)
  Instalment from the sheet; start date, paid-off date and the settled toggle are
  human-entered and preserved across re-seeds. Months-left and outstanding are
  null until a date is entered, never R0 on a live debt. The two paid-off
  agreements (WB02, DT01) show as settled and are excluded from the run-rate.

Purchases + Oil Stock
  Uploads PO PDFs the way /income/invoices does. The parser reads columns by
  x-position, because plain text extraction reorders them, and refuses any PO
  whose lines do not sum to the sub-total. A cost code either names a machine
  ("SS-02" -> SS02) or a stock store ("MPLANT, ENGOIL") — never both, never
  guessed. Oil POs move litres into oil_stock_movements instead of onto a machine;
  stock is the sum of movements so the first usage is a subtraction from history.

Operators (19) and Mechanics (2)
  Both are people with an employee number, separately reconcilable by the seed so
  someone added in the app survives. Mechanics get a badge QR; a mechanic with no
  employee number cannot be printed, because the code is what the QR encodes.

Cross-cutting
  - The seed no longer deletes operators, mechanics or oil items: people are added
    in the app, and those rows exist in no file.
  - Re-pointing allocations that PocketBase clears because `assets` is rebuilt
    with new ids each seed (operators, purchase lines).
  - One QR encoder for screen and PDF, so a printed code cannot drift from the one
    on screen. pdf-lib writes real vector PDFs; pdfjs-dist only reads them.
  - Every figure is null-safe: unknown is never rendered as zero.

* A QR drawn from the shared matrix in `lib/qr.ts` — the SAME encoder the PDF uses.
*
* Never swap this for a QR widget component. The encoder produces the raw module
* matrix, which lets the screen and the printed file come from one source; a widget
* would render its own and the two could drift, and a badge whose printed code
* differs from its on-screen code identifies the wrong person or the wrong drum.
