Improve telemetry batching

[akhenry]

• [x] Swap Open MCT dependency back to "unstable" once https://github.com/nasa/openmct/pull/7526 has been merged.

Closes https://github.com/akhenry/openmct-yamcs/issues/424

Describe your changes:

• Install remote clock to allow more flight-like testing, but leave Local Clock as the default.
• Auto-fixed some linting errors that snuck into master in binaryToHexFormatter so ignore those changes.
• Renamed rate to maxBatchWait to improve clarity.
• Added extensive e2e tests to verify that Open MCT:
  • Does not drop telemetry while loading (the original issue)
  • Always displays the latest data according to Yamcs
  • Drops telemetry when UI is under sufficient load, and warns the user
  • Reconnects after a WebSocket dropout, and re-subscribes (good catch @shefalijoshi !)
