build: disable parallel testing locally, add test db setup target

- Remove --parallel flag from test/test-unit/test-feature in Makefile
- Remove --parallel flag from test scripts in composer.json
- Add setup-test-db target for manual database creation
- Parallel testing reserved for CI only (--ci --parallel)
- Local runs use serial mode for simpler debugging
