rebase: apply audit bug fixes on latest main

Rebased fix/1.0-audit-bugs onto current main (post-merge of PRs #119, #127).

Changes:
- Custom domain types: docker.ImageID, docker.ContainerID, webhook.UnparsedURL
- Type-safe function signatures throughout docker/deploy/webhook packages
- Remove docker-compose.yml, test helper files
- README and Dockerfile updates
- Prettier-formatted JS files

-**Important**: When running µPaaS inside a container, set `UPAAS_HOST_DATA_DIR` to the host path
+**Important**: Set `HOST_DATA_DIR` to an **absolute path** on the Docker host before running
-that maps to `UPAAS_DATA_DIR`. This is required for Docker bind mounts during builds to work correctly.
+`docker compose up`. Relative paths will not work because docker-compose may not run on the same
+machine as µPaaS. This value is used both for the bind mount and passed to µPaaS as
+`UPAAS_HOST_DATA_DIR` so it can create correct bind mounts during builds.
+
+Example:
+```bash
+export HOST_DATA_DIR=/srv/upaas-data
+docker compose up -d
+```
 
 Session secrets are automatically generated on first startup and persisted to `$UPAAS_DATA_DIR/session.key`.
