* For habit reset logic, changed day check calculation to use user’s timezone instead of server time.
Added unit tests to check following cases:
- Weekly habit reset: Server tz is Sunday, User tz is Monday
- Weekly habit reset: Server tz is Monday, User tz is Sunday
- Monthly habit reset: Server tz is 1st of month, User tz is 2nd of month
- Monthly habit reset: Server tz is end of prev month, User tz is 1st of month
* use moment().zone() instead of utcOffset()
* typo
* Fixed check for daysMissed, added logic for CDS
Added test for CDS, fixed previous tests
