feat: 스니펫 공용화 — 서버 PostgreSQL 테이블 + API, 프론트는 브릿지 대신 HTTP

결정(9/21): 공용 하나, 개인 로컬 없음.
- backend apps/snippets: Snippet(name PK·desc·body·category) + SnippetUsage(사람별 count/last_used).
  GET/POST /api/v1/snippets, PUT/DELETE /snippets/{name}, POST /snippets/{name}/use — 옛 브릿지 5개와 1:1,
  이름 정규화·중복 409·빈 내용 400 규칙 동일. import_snippets 커맨드로 옛 snippets.db 적재. 테스트 3개
- frontend snippets.api.ts 만 HTTP 로 교체(훅·페이지·타입 무변경). 테스트 axios-mock-adapter 로
- ponytail: Tauri 로컬 SQLite 커맨드는 미사용 상태로 남김. 지울 때 Rust+브릿지 테스트 함께
