Migrate User Status Data from Old Structure to New Format in Firestore

Issue Description

We need to migrate existing user status data from the old structure in usersStatus to the newly proposed structure, which separates user status into usersStatus and usersFutureStatus collections. The goal is to ensure that all past, current, and future statuses are correctly represented in the new system.

Expected Behavior

• All old user status data should be migrated.
• The new structure will store past, current, and future statuses separately, allowing us to track historical events.
• Future statuses will be stored in usersFutureStatus with proper fields such as from, endsOn, and state.

Current Behavior

• User status is currently updated in place in the usersStatus collection, overwriting past statuses.
• Future statuses are stored within the same document, and events are not logged.
• The current system does not handle status transitions, such as applying future statuses automatically.

Severity/Priority

• Critical
• High
• Medium
• Low
