Waiting users audio and push alerts

Backport audio improvements from 2.3

Revert "Add reconnection and sync handler"

Revert "Fix clear chat for single message"

Without 'exact' match, the browser fallbacks to the default inputDeviceId

This prevents the error (input device error)  when breakout is ended and we try
to skipCheck the microphone when user returns to main room (assuming the
user had the microphone active before joining breakout room).

Prevent toggleMute api call to be called for listenonly
This has no effect to the end user, but avoids unnecessary server calls

Fix padId getter

Pad exporter uses this same location to serve pad's downloaded content
but the the match was failing because padId is not the last element
of the URL on that scenario.

Pattern follows /pad/p/<padID>[/export/(format)]?<query>.

numUsersVideo being undefined breaks layout

Fix svg width error

Since we added audio alert notifications in settings controls there was an ampty
grid gap reserved for the push alerts.

Debounce could make the behaviour of "not always ringing when a guest
enters" feel "buggy". Throttle makes it clearer that it happens to
prevent it from ringing too frequently.

Also move Throttle time from magic number to constant for
a meaningful variable name.
