feat(review,teams): review foundation — segments, side-by-side editor, rebuild, XLIFF, team workspaces

Foundations:
- TranslationSegment model + migration f7e8d9c0b1a2 (segments, workspaces,
  workspace_members, glossaries.workspace_id)
- SegmentRecorder injected into all 4 translators: unique (source,
  translation) pairs captured per job and persisted (best-effort)
- set_segment_overrides: human-reviewed translations applied verbatim on
  rebuild — top priority over TM and provider, zero API calls

Review API (routes/review_routes.py):
- GET /translations/{id}/segments (owner or job token)
- PATCH /segments/{id} edit/approve — feeds the per-user TM so approved
  translations are reused in later jobs
- POST /translations/{id}/rebuild — rebuild document with reviewed text
- GET/POST /translations/{id}/xliff — XLIFF 1.2 export/import (edited
  segments export their reviewed text)

Review editor (frontend /dashboard/reviews/[jobId]):
- side-by-side source/translation table, inline edit, approve (single or
  all), rebuild & download (auth blob), XLIFF export/import, 13 locales
- 'Relire et corriger' link on the translation-complete screen

Team workspaces (routes/workspace_routes.py + /dashboard/teams):
- Workspace/WorkspaceMember models, roles owner/admin/member
- create (Business plan), list with seat usage, invite by email with
  seat-limit enforcement (Business=5, Enterprise unlimited), removal
- shared glossaries: workspace members can use a glossary shared to their
  workspace (access check extended)

Tests: 1184 passed / 0 failed (11 new: recorder, overrides, docx
capture->rebuild e2e, XLIFF structure/escaping, seats, workspace CRUD,
shared glossary access)
