* refactor: Update booking query to use userId and optimize availability check logic
- Changed the booking query to use userId instead of nested user object for filtering active bookings.
- Refactored availability check logic to improve readability and performance by using valueOf() for time comparisons and consolidating multiple checks into a single return statement.
* fix: update tests
* chore: use toDate()
* tests: add checkavailable unit tests
