Add countdown timer for API post delay

- Changed "Waiting for API post" to "Wait to post API"
- Added countdown display from 7s to 0s during API post delay
- Implemented startApiCountdown, stopApiCountdown, and updateApiCountdownStatus functions
- Added state variables apiCountdownTimer and apiPostTime
- Countdown updates every second similar to auto-ping countdown
- Clean up API countdown timer on disconnect
