fix: self-heal watchdog missed the genuinely-paused failure mode

The frozen-frame check required !vid.paused, assuming playback would be
stuck while playing. The actual failure is the element sitting genuinely
paused (play() still not reliably unblocked), so that guard was never true
and the watchdog silently did nothing. Removed the paused requirement and
added console diagnostics on every tick so the next test gives concrete
evidence if this still doesn't fully resolve it.
