feat(dimensions): PR7 producers — auto-tagged documents (invoices, supplier invoices, bulk-book, templates, MCP) (#868)

* feat(dimensions): PR7 producers — invoices/supplier invoices carry dims, generators propagate, BulkBook + templates + MCP bags

Source documents now carry dimension tags and every entry generator
propagates them onto journal lines (dev_docs/dimensions_implementation_plan.md PR7):

- invoices/supplier_invoices.default_dimensions + per-item dimensions
  (migration 20260702200000; jsonb DEFAULT '{}' + object CHECK)
- invoice-entries: issuance/payment/cash/credit propagate — item bags merge
  over the invoice default per revenue line (account+bag aggregation
  identity), payment vouchers re-propagate the linked invoice's bag onto
  every leg incl. FX result lines; ROT/RUT 1513 carries the item bag
- supplier-invoice-entries: registration/payment/cash/privately-paid/credit
  propagate with the same merge rules (expense buckets keyed account+bag)
- bulk_book_transactions RPC persists per-line bags + derives
  cost_center/project mirrors in SQL (migration 20260702201000; malformed
  bags rejected with BULK_BOOK_INVALID_DIMENSIONS); route merges the header
  default into template/manual lines
- counterparty templates: LinePatternEntry.dimensions learned from SIE
  voucher history (kept only when every occurrence agrees), applied to
  business lines on booking; QuickReviewDialog shows a dims badge
- categorize: staged dimensions bag tags business lines only (bank/VAT
  untagged); credit/convert/inbox copy paths carry bags forward
- propose-payment/send-lines stamp the invoice default so the editable
  payment grid books what the preview shows; mark-paid override lines
  accept dimensions
- UI: InvoiceEditor + NewSupplierInvoiceForm header KS/Projekt pair with
  per-row override; BulkBookDialog header default pair (both tabs)
- MCP: default_dimensions/items[].dimensions on create_invoice +
  create_supplier_invoice_from_inbox, dimensions on categorize_transaction,
  per-line bags on bulk_book_transactions — resolve-don't-select via the
  shared registry helpers, resolutions echoed

32 new propagation unit tests + 4 pg-real tests for the RPC migration.
