feat: ADR-0035 Amendment 1 follow-up — enrich replay errors + close message gaps

- F2-broad: replay failures now render with real schema context instead of
  a contextless friendly_message(). Extract App::build_translate_context into
  the shared App::translate_context_for(command, facts, verbosity); run_replay
  enriches via enrich_dsl_failure + that builder. ctx_* fallbacks degrade to
  neutral prose so the rare non-replay contextless callsites can't leak raw
  {name} either. (SQL INSERT/UPDATE values aren't retained — ADR-0033 verbatim
  — so those show real table/column + neutral "that value".)
- Gap C: SQL ALTER … ADD FOREIGN KEY on a missing child column refuses with an
  SQL-appropriate "add it first", not the DSL-only --create-fk flag.
- Gap B: dropping a single-column-UNIQUE column refuses with a pointer to
  `drop constraint unique from T.col` (was an opaque generic refusal).
- Gap D: 4e drop/rename CHECK-guard + 4f change-type FK-guard refusals reworded
  to explain why; static_refusal reasons left as-is.

Tests: +4, 3 strengthened. 1926 pass / 0 fail / 0 skip; clippy clean.
