Store Points from Questionnaire

[sun-415]

Updated user story: As a user, I want my total points to be saved, so that my progress accumulates over time even if I log out, refresh, or return to the app on a different day.

Acceptance Criteria:

• Take the total points user just received from filling out the day's questionnaire and add it to the total accumulated points saved in the backend, associated with the user’s unique account ID.
• Save this new total accumulated points in the backend(if storing the total accumulated rather than total points for each day)
• Data persists in the backend so that it remains available for future sessions, even if the user logs out or refreshes the app.

Estimate: 1-2 weeks

Code review Request: The code changes is in the branch Connected CheckIn to Backend. Need to replace userID with the unique account ID generated by Google Login for it to be functional.
