Add Activity Spinner to telemetry operations.

We should implement an 'activity spinner' and retransmission feature for when setting parameters and sending commands. The APM will send a command_ack or confirm the parameters new value. If we don't get it, we should resend the parameter again and increment the confirmation number, for a limited number of retries. For commands which should fail and display the result code, and restore the previous state (if required)

This will help with some visual cues for user, since you can be left wondering if anything is happening, for example when Trigger level etc....

The issue names no files, tests, or entry points, so begin by locating the telemetry parameter-setting and command-sending paths in APM Planner. Define the spinner, acknowledgement or confirmation handling, bounded retransmission, failure result display, and any required state restoration before implementation. Done means these operations provide visible progress and handle success and failure as described.
