feat: auto-discover container images from registries

- Add ListImages() to registry interface, implement for Gitea
- Add owner field to registry config (needed for Gitea packages API)
- GET /api/registries/:id/images endpoint
- "Browse Images" button on Projects and Quick Deploy pages
- Image dropdown with registry grouping and search
- i18n support (EN/RU) for all new UI strings
