Step 1: i18n foundation (@angular/localize) + data inventory

Domain reference data already lives in the backend (per ADR-0001); the only
residual "move" was ~90 inlined Dutch UI strings with no i18n layer.

- Wire @angular/localize ($localize) — Angular first-party, no third-party lib
- Pin the pattern on shared/ui/async: Dutch fallbacks → language-agnostic
  input()s with localizable $localize defaults (English-shared-UI rule)
- CLAUDE.md: drop i18n (now in scope) + stale "real backend"/"OpenAPI codegen"
  (both already shipped); document the $localize convention

Bulk string sweep deferred to Step 2 to avoid touching ~36 files twice.
