fix(library): visibility hover + workspace filter + tab Repository pour Gitea

- CSS hover-only: visibility:hidden/visible au lieu de opacity (infaillible)
- Workspace tab: filtré par workspace_id quand un workspace est actif
- Tab Private remplacé par Repository (visible seulement si Gitea workspace actif)
- Nouvel endpoint /api/library/repository pour le contenu Gitea
- dashboard.py passe is_gitea_workspace, owner, repo au template
