feat(jwt): Improve JWT expiration handling and fix naming conflicts

• Replaced time.time() with datetime.datetime.utcnow() to ensure accurate expiration handling.
• Used datetime.timedelta(seconds=...) for better timestamp calculations.
• Ensured compatibility with jwt.encode() by converting expiration times using .timestamp().
• Renamed algorithm to jwt_algorithm to avoid conflicts with the ALGORITHM constant and ensure consistency.

test(twilio): Add unit test for Twilio Video Room creation

• Integrated unittest framework for structured testing.
• Used responses library to mock Twilio API calls.
• Implemented a test case that validates room creation by checking sid, unique_name, and status.

These changes enhance JWT handling, resolve potential naming conflicts, and introduce automated testing for Twilio API interactions.

Fixes #777

Summary of Changes

This PR addresses the following improvements:

• Fix for Issue Code Enhancement #777 (JWT Expiration Handling):

  • Replaced time.time() with datetime.datetime.utcnow() to ensure accurate expiration calculations.
  • Applied datetime.timedelta(seconds=...) to improve timestamp consistency.
  • Ensured compatibility with jwt.encode() by converting expiration times using .timestamp().
  • These changes improve time handling accuracy, ensuring JWTs expire correctly across different time zones.

• Resolved SonarCloud issue (Naming Conflict with ALGORITHM):

  • Renamed algorithm parameter to jwt_algorithm to prevent confusion with the ALGORITHM constant.
  • This improves maintainability by avoiding case-sensitive conflicts in variable names.

• Added a new unit test for Twilio Video Room creation:

  • Integrated unittest framework for structured testing.
  • Mocked Twilio API calls using the responses library.
  • Verified room creation by checking sid, unique_name, and status.
  • Note: Existing tests already cover the JWT expiration fix, so no additional tests were needed for that.
