v3.0.1: qualité & stabilité — tests, sécurité, UX consolidée

🧪 Tests: 73 → 130 (+57 tests)
- Upload API, labels sync, commit history (401/400/502/cached)
- File create/update (sha=null, sha=abc)
- Admin delete cascade (12 tests: oauth, tags, workspaces, pages…)
- Gitea status (linked/unlinked/disconnect)
- OAuth link mode (session, redirect, callback)

🔒 Sécurité
- ContentSecurityPolicyMiddleware (CSP headers)
- RateLimitMiddleware (100 req/min/IP)
- Pydantic models: ErrorResponse, SuccessResponse
- Input validation upload (10MB, allowed extensions)
- Pydantic request models

🎨 UX
- static/css/design-tokens.css (500 lines, thèmes + skeletons)
- Toast system: 16 alert() remplacés par toast()
- 59 lignes CSS dupliquées retirées (6 templates)
- Skeletons cohérents sur toutes les vues

⚡ Performance
- Cache TTL sur get_file_commits (consistant avec les autres méthodes)
