chore(cleanup): with litestream we can remove any communication with …

…S3 from the service

Also updates docker-compose so one can easily spin up the service and litestream if they wish

 You can run on a different port by changing the `-e PORT=3000 -p 3000:3000` to `-e PORT=4000 -p 4000:4000`, for example, or specify a `.env` file with `--env-file` flag.
 
+#### Profiles
+
+The service can be run with different profiles to facilitate different environments. The following profiles are supported:
+
+- `test`: runs the service and other containers for executing integration tests
+- `litestream`: runs the service with [Litestream] for syncing SQLite data to S3
+
+To run the service with a profile, you can use the `--profile` flag:
+
+```shell
+docker compose --env-file .env --profile litestream up --build

 - `ARNS_CONTRACT_TX_ID`: the ArNS contract transaction ID. Defaults to `bLAgYxAdX2Ry-nt6aH2ixgvJXbpsEYm28NgJgyqfs-U` and when `PREFETCH_CONTRACTS` is `true`, will be prefetched on startup.
