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

Squashed Phase-2 SSR work: migrate the Transaction Edit modal's render path
entirely to Selmer templates (zero Hiccup in the render path), rip out the
multi-step wizard abstraction (EditWizard/LinksStep records, MultiStepFormState,
step-params[...] field names, mm/* middleware) in favor of a plain form with
flat derived state, and promote shared UI components to reusable Selmer partials
under resources/templates/components/. Adds the Selmer interop bridge, the
auto-ap.ssr.components.selmer (sc) wrapper library, and the ssr-form-migration
skill capturing the learnings.
