Logic: Implemented "One User, One Bin" locking to prevent duplicate counting.
Integrity: Standardized is_deleted = 0 and tightened "Matched" criteria to require zero weight variance.
Refresh: Added silent 30-second dashboard polling for all 6 status categories and active counter list.
Tracking: Built user-specific activity tracking to identify who is counting where in real-time.
Stability: Resolved persistent 500 errors by finalizing the active-counters-fragment structure.
