FCE-3295: Fix media event queue order catch (#530)

## Description

- `webRTCEndpoint.ts`: chain `.catch()` before `.then()` on
`mediaEventQueue` so a rejected prior event doesn't propagate the same
rejection to every subsequent `receiveMediaEvent` caller.

## Motivation and Context

Previous order assigned the caught queue back to `mediaEventQueue` but
returned the uncaught `next`, so one failed handler would reject every
queued event after it. Catching first keeps the queue alive and isolates
failures to their own caller.
