`tick()` in `rateLimitStore` is never called — the countdown never decrements

[therealjhay]

File: lib/store/rateLimitStore.ts

The tick() function exists but is never invoked by any component. Create a useRateLimitCountdown hook that calls tick() every second using setInterval when rateLimitedUntil > 0. The hook should clean up the interval on unmount. This ensures the secondsRemaining in the store decrements in real time.
