MuteDeck Browser Extensions v6.3.0 (reliability fixes)

Fixed an empty popup. On a meeting tab, the extension popup could sometimes open with the status labels but no values. It now recovers automatically, and if it still can't connect it shows a clear message with a button to reload the page.
Meetings reconnect after updates. Previously, if the extension updated while you had a meeting tab open, that tab would stop responding (status and Stream Deck controls) until you reloaded the page. Open meetings now reconnect on their own — no page reload needed.
Fixed the mute status in the popup. The popup could sometimes show "Muted" even when you were unmuted. It now reflects your real microphone state. (This only affected the popup display; reporting to the MuteDeck app was always correct.)
