Add friendly names system for recipes, effects, and media

- Add friendly_names table with unique constraints per actor
- Create NamingService with HMAC-signed timestamp version IDs
- Version IDs use base32-crockford encoding, always increase alphabetically
- Name normalization: spaces/underscores to dashes, lowercase, strip special chars
- Format: "my-effect 01hw3x9k" (space separator ensures uniqueness)
- Integrate naming into recipe, effect, and media uploads
- Resolve friendly names to CIDs during DAG execution
- Update effects UI to display friendly names
- Add 30 tests covering normalization, parsing, and service structure
