feat(search): smart JSONB search across all dictionaries

CEO plan v1 stretch — закрывает gap "Smart JSONB search across all dictionaries".
Last gap из v1 list shipped.

Migration 0018:
- CREATE EXTENSION pg_trgm (CNPG initdb обычно не enable'ит, добавили
  явно с MARK_RAN preCondition если уже есть).
- CREATE INDEX idx_dict_records_data_trgm
    ON dictionary_records USING GIN ((data::text) gin_trgm_ops)
- Trigram-based ILIKE с минимум 3 символа в query — index используется.
  ILIKE '%pat%' на data::text возвращает любые matches в JSONB serialized.

Backend:
- New RecordSearchQuery (ordinis-domain): native SQL c ROW_NUMBER()
  per-dict cap. SQL injection защищён PreparedStatement param + extension
  whitelist (allowed_scopes — text[]).
- New SearchController (ordinis-rest-api): GET /api/v1/search?q=&size&perDict.
  Default size=100, perDict=10. Min q length=3 (silently empty if shorter).
  Scope filtering through ScopeContext — каждый caller видит только свои
  scope levels. Results grouped per dict с display name + count + items.

Admin UI:
- New /search route с SearchInput + grouped Panel results.
- URL state ?q=… — share-friendly link "/search?q=SAR-X".
- Per-result link → /dictionaries/{dict}?q={businessKey} для drill-down.
- Min-3 hint, empty state, loading + error.
- New "Поиск" / "Search" tab в navigation header.
- i18n RU (с правильными plurals search.totalHits) + EN.

Behavior:
- Active records only (valid_from <= now() < valid_to).
- Per-dict cap 10 — защита от dominant-dict skew (один dict с 1000 matches
  не забьёт результат).
- Total cap 100 — admin "find this code" use case достаточно. Browser-style
  search-as-you-type (10k+ matches, instant) — отложен на v2 с dedicated
  index server (Elastic / Meili).

Verify:
- mvn -P e2e -pl ordinis-app -am test: 20/20 PASS (migration applied).
- pnpm tsc --noEmit: clean.
- pnpm test (vitest): 89/89 PASS.
- pnpm build: clean.

После migration apply'я index size на dictionary_records будет ~30-40%
data column. На текущих 5k records ~3-5 MB, acceptable.
