Fix media friendly names, metadata display, output recording, and plan display

- Add friendly name display to media detail and list pages
- Unpack nested meta fields to top level for template access
- Fix output_cid mismatch: use IPFS CID consistently between cache and database
- Add dual-indexing in cache_manager to map both IPFS CID and local hash
- Fix plan display: accept IPFS CIDs (Qm..., bafy...) not just 64-char hashes
- Add friendly names to recipe listing
- Add recipe upload button and handler to recipes list
- Add debug logging to recipe listing
