feat: tag management — scrape, edit, search existing, import to Mealie/Tandoor

- Scraper extracts tags from mindmegette.hu (<a class="tag">) and schema.org keywords
- Tag editor UI with removable chips, search/autocomplete for existing tags, custom add
- Mealie: auto-create tags via POST /api/organizers/tags, include in recipe PATCH
- Tandoor: include keywords in recipe POST (auto-created by name)
- New GET /tags endpoint returns existing tags from both services for search
