Fix recipe listing, effects count, and add nav counts to all pages

- Fix list_by_type to return node_id (IPFS CID) instead of local hash
- Fix effects count on home page (count from _effects/ directory)
- Add nav_counts to all page templates (recipes, effects, runs, media, storage)
- Add editable metadata section to cache/media detail page
- Show more metadata on recipe detail page (ID, IPFS CID, step count)
- Update tests for new list_by_type behavior
