Enable CGO for all GoHoarder binaries to support SQLite

Changes:
- Set CGO_ENABLED=1 for gohoarder main binary in .goreleaser.yaml
- Add sqlite-libs and musl to Dockerfile.server
- Add sqlite-libs and musl to Dockerfile.scanner

All Go binaries that interact with SQLite now have CGO enabled:
✅ gohoarder (main binary) - used by server and scanner
✅ migrate (migration tool)

Runtime containers include necessary C libraries:
✅ Dockerfile.server - SQLite runtime support
✅ Dockerfile.scanner - SQLite runtime support
✅ Dockerfile.migrate - SQLite runtime support

This fixes: 'Binary was compiled with CGO_ENABLED=0, go-sqlite3 requires cgo'
