SQLite writes three files — the database plus its -wal and -shm companions.
Putting them in one directory means a deployment mounts a single path and a
backup copies a single directory.
- FOODSTER_DB defaults to ./data/foodster.db, and openDB creates the parent
directory on startup rather than failing on a fresh checkout
- compose bind-mounts ./data instead of using a named volume, so the file can
be listed, copied and opened with any sqlite client without going through
the container engine
- the image runs as UID 65534, which cannot write to a host directory owned
by someone else, so compose now sets user: from FOODSTER_UID/FOODSTER_GID
- `make up` creates ./data first: left to the engine it appears root-owned
and the app silently cannot write to it
