If drawer.tsx is unused - edited

If drawer.tsx is unused: v- edited
- Remove components/ui/drawer.tsx.
- Remove related exports.
- Remove vaul from dependencies.
- Update lockfile properly.

After implementation, guide me to test:
- Search commands to confirm no Drawer/vaul references remain.
- Package install command if lockfile changes.
- Typecheck/lint/build commands.
- Any UI routes to manually verify where Sheet/modals are used.
