feat(V2-3차): pull 확장 + invite flow + Realtime + 테스트 + mobile UI 교체

묶음 E — V2-4b pull 확장:
- CloudSyncService.pullAll()에 meetings/meeting_memos/meeting_documents 추가
- meetings: LWW, 모든 컬럼 매핑 (minutes_json JSON 직렬화)
- meeting_memos: immutable INSERT-only 전략
- meeting_documents: LWW UPDATE

묶음 F — api-client types:
- interface -> type alias 전환 (11개)
- Database 타입에 TypedTable<Row, Insert, Update> 유틸 도입
  (Row & Record<string, unknown> 교차로 GenericTable 제약 만족)
- @supabase/ssr 2.102는 supabase-js 버전 불일치로 제네릭 주입 불가 -
  다음 사이클로 이월, api-client index.ts는 types만 재수출

묶음 G — apps/mobile UI 교체:
- login.tsx: MetalCard + PhosphorText(hero/label) + PhysicalButton
- meetings.tsx: MetalCard + Led(status) + PhosphorText(body/meta)
- record.tsx: Led + PhosphorText + PhysicalButton
- profile.tsx: MetalCard + PhysicalButton(danger) + d3roNativePalette

묶음 H — V2-7b 이메일 invite flow:
- migrations/20260410000001_team_invites.sql
  - team_invites 테이블 (token, email, role, expires_at 7일)
  - RLS: 같은 팀 멤버 + 초대 이메일 소유자 SELECT,
    owner/admin만 INSERT/DELETE
  - generate_invite_token() SECURITY DEFINER RPC (service_role)
- functions/team-invite: 권한 체크 -> 토큰 생성 -> 초대 URL 반환
- functions/team-accept: 토큰 검증 -> expires_at/accepted_at/이메일 일치 ->
  team_members upsert -> 초대 accepted 표시
- config.toml에 team-invite/team-accept 함수 등록
- InviteMemberForm 재작성: 이메일 입력 + 역할 선택 -> URL 복사 UI
- /accept-invite 페이지 신규 (Suspense 내 useSearchParams + token 수락)

묶음 I — Realtime transcripts:
- apps/web/components/meetings/live-transcript-list.tsx (client)
  - supabase.channel('transcripts:meeting:${id}').on('postgres_changes')
  - INSERT -> 세그먼트 추가, UPDATE -> row 교체
  - 중복 방지 segment_index 기준
  - edited 배지 표시
- meetings/[id]/page.tsx의 transcript 섹션을 LiveTranscriptList로 교체

묶음 J — 테스트:
- packages/api-client/__tests__/client.test.ts (9 tests)
  - createD3roSupabaseClient, isClientConfigured 팩토리 검증
- packages/api-client/__tests__/types.test.ts (10 tests)
  - 모든 Row 타입 + 리터럴 union + Database keyof
- vitest.config.ts 신규
- apps/web/playwright.config.ts 신규 (baseURL, webServer dev 서버)
- apps/web/e2e/smoke.spec.ts 신규 (6 스모크 테스트)
- apps/web tsconfig exclude에 e2e/playwright.config.ts 추가
- package.json scripts: test, test:e2e, test:e2e:ui

검증:
- desktop typecheck OK
- web typecheck OK
- web next build OK (12 라우트, /accept-invite Suspense 적용)
- desktop build OK
- api-client test 19 passed
