[fonts] Stop loading all fonts into memory at service startup

- AssetCollection now holds a bidirectional map of buffer IDs and paths to font files
- Removed AssetCollection.assets cache in favor of relying on filesystem behavior (VFS can already manage caching and handle-counting)
- Expect slightly more disk reads (previously: read all files exactly once; now: read all files once at startup + individually as needed)
