♻️(frontend) prefer captureMediaEvent over reportError when no-op

Switch calls to `reportError` over to `captureMediaEvent` when the
underlying situation is not an engineering issue to investigate but
rather a media-related event worth tracking (e.g. no camera or
microphone available on the user's device).

`reportError` stays reserved for actual errors that warrant an
engineer's attention.
