Timer & positioning improvements; File size fixes.

Previously, the countdown timer/size area was not visible anymore when the bottom menu was disabled (showmenu=0). Now, it stays at the top of the recording client regardless of the bottom menu’s visibility.

When the bottom menu was hidden (showmenu=0), the bottom right device selector buttons had a bigger bottom margin than necessary. This has been rectified, and they are now appropriately spaced, ensuring a cleaner layout.

Fixed the issue with the recorded file size resetting to 0 after the recording process was stopped.
