fix: Correct user role permissions and restrict dashboard/settings access

- Fix setupUIForRole selector to use correct data-tab attributes
- Hide Dashboard and Settings tabs for regular users (non-admin)
- Remove delete buttons from sales table for regular users
- Set initial tab to 'Ventas' for regular users instead of Dashboard
- Add comprehensive logging for role setup debugging
- Update cache buster to v=101.0 for proper browser refresh

Security improvements:
- Regular users: Access to Ventas, Clientes, Productos only
- Admin users: Full access to all sections including Dashboard/Settings
- Proper enforcement of user role restrictions in UI
