- Update `entrypoint.sh` to support `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_NAME` environment variables for dynamic DSN construction.
- Ensure proper escaping of special characters in `entrypoint.sh` when using `sed`.
- Update `Dockerfile` to accept `GOPROXY` build argument.
- Update `Dockerfile` to include `curl` in runtime image for debugging.
- Use `-ldflags="-s -w"` in `go build` to reduce binary size.
- Downgrade Go version from 1.25.1 to 1.24.0 in go.mod and Dockerfile to resolve build failure (Go 1.25 is not yet released).
- Add `netcat-openbsd` to Dockerfile runtime image to ensure `nc` command is available for health checks.
- Update `entrypoint.sh` to robustly wait for `stunnel` to start using `nc` loop, preventing app startup failure when DB TLS is enabled.
- Add explicit error handling in `entrypoint.sh` if `stunnel` fails to start within timeout.
