fix: resolve flaky holiday hours test and clean up dev scripts

- Use fixed date (Thursday Feb 26, 2026) instead of dynamic tomorrow
  to avoid timezone-related test flakiness
- Remove orphaned SQL fragment from init-script.sql
- Clean up duplicate color code definitions in local-dev-2.sh
- Add Rustfs data wipe and SabreDAV startup to dev script
- Add composer.lock to .gitignore
