feat: v6.2.0 Web Clipper — extension navigateur (capture article/selection/bookmark/screenshot)

- Service app/services/web_clipper.py: sanitize HTML, html->blocks, extraction article, creation page workspace-aware, rate limit 50/h, device registration
- Router app/routers/web_clipper.py: POST /api/v2/web-clipper/clip, GET /status, POST /auth/verify, GET/DELETE /devices, GET /extensions (download page), auth via session ou Bearer (api_tokens / extension_devices)
- Migration 19: extension_devices + extension_clips (+ indexes)
- Extension Manifest V3: content.js (floating button, selection), background.js (clip + contextMenus), popup.html/js, clipper.css, icons
- Settings UI: onglet Extensions (liste devices, revoke, test clip, liens download), page /extensions
- Tests: 16 tests web_clipper (sanitize, blocks, article/bookmark/selection/screenshot, bearer, rate-limit, devices, extensions page)
- Bump version 6.1.0 -> 6.2.0
