Changed Timer Placement

The timer in the recording client has been relocated from the bottom to the top. It now features a dark background, and while recording, a red dot is dynamically displayed next to it. The timer now functions as a counter-up, starting from 0, progressing up to the maximum recording time (e.g., “00:00 / 10:00”). In playback mode, a play or pause icon appears next to the timer, reflecting the playback status.
