refactor(ssr): full Selmer migration of Transaction Edit; remove the wizard

Migrate every part of the Transaction Edit modal's HTML to Selmer templates
(zero Hiccup in the render path) and delete the mm multi-modal "wizard"
abstraction entirely -- there was only ever one step.

- New auto-ap.ssr.components.selmer (sc) + ~22 shared component partials under
  resources/templates/components/ (typeahead, button-group, radio-card,
  data-grid, validated-field, modal, buttons, inputs, SVGs). Each wrapper renders
  its own partial; dynamic HTMX/Alpine attrs bridge via attrs->str -> {{attrs|safe}}.
- 15 modal templates under resources/templates/transaction-edit/.
- Delete EditWizard/LinksStep records + all mm/* usage. Plain handlers: flat
  wrap-decode-edit (fields renamed off step-params[...], stray keys stripped),
  flat wrap-derive-state, *errors*-based field errors, generic wrap-form-4xx-2.
- Drop the edit-wizard-navigate route (routes ~12 -> 5).
- Fix: stray `method` (tab button-group hidden) leaked into the upsert -> 500;
  strip decoded map to schema keys.
- e2e selectors updated (#wizard-form->#edit-form, #wizardmodal->#editmodal,
  step-params[...] field names). Parity: swap 6/6, edit 8/8, suite 38/1
  (1 pre-existing unrelated nav test).
- ssr-form-migration skill updated with the learnings (composition mechanics,
  sc/* library, drop-the-wizard recipe, scorecard row, 3 new gotchas).
