schema: add ON DELETE CASCADE to snapshot_files.file_id and snapshot_blobs.blob_id FKs (#46)

Browse Source 
Add `ON DELETE CASCADE` to the two foreign keys that were missing it:

- `snapshot_files.file_id` → `files(id)`
- `snapshot_blobs.blob_id` → `blobs(id)`

This ensures that when a file or blob row is deleted, the corresponding snapshot junction rows are automatically cleaned up, consistent with the other CASCADE FKs already in the schema.
