bug: Standardize timezone boundaries and evaluate active-hour grace periods for streaks

[MasterJi27]

Resolves #5258 and Resolves #5260. Standardizes local timezone boundary mappings by checking midnight ranges in local dates, and ensures that active-hour grace periods are evaluated correctly before breaking streaks.

@MasterJi27 is attempting to deploy a commit to the jhasourav07's projects Team on Vercel.

A member of the Team first needs to authorize it.

Thank you for reviewing and approving my PRs.

Currently, I have the following approved PRs open:

#5364 – bug: Sanitize MongoDB operators from user-tracking payloads
#5343 – bug: Standardize timezone boundaries and evaluate active-hour grace periods for streaks
#5338 – bug: Align historical year ranges to user timezone offsets
#5286 – perf: Implement request coalescing (single-flight) for user contributions fetching
All of them have been reviewed and approved. The remaining blocker appears to be Vercel deployment authorization.

Could someone from the team please authorize the Vercel deployment and merge these PRs when convenient? It would help me continue working on additional assigned issues without having multiple approved PRs pending.

Thank you!
