feat(categorize): dimension bags end-to-end + runtime template learning (#1273)

* feat(categorize): dimension bags end-to-end + runtime template learning

The categorize path could not tag: categorize-core accepted a dimensions
bag but no route or UI ever passed one, and runtime template learning
dropped the bag entirely (only SIE import produced dimension-carrying
patterns).

- CategorizeTransactionSchema gains dimensions; the dashboard route, v1
  single and v1 batch-categorize apply it to the mapping result's
  business lines (explicit bag wins over a learned counterparty bag).
- categorization_templates.default_dimensions (migration 20260728091000)
  records the bag of the latest tagged booking; latest-explicit-wins, an
  untagged booking never erases it. Applied on the legacy single-line
  template path and the mirrored-refund path; multi-line SIE patterns
  keep their authoritative per-entry bags.
- QuickReviewDialog gets a LineDimensionFields picker (dimensions_enabled
  gate, same as BulkBookDialog), prefilled from the counterparty
  suggestion's learned bag; hidden for multi-line patterns whose per-line
  bags would ignore an edit.
