getByIndex allocates memory and returns dummy channel whenever
chIndex validation fails. Comment implies this may happen
when malformed packet is received. The fix changes implementation
so static dummyChannel is returned in such case.

* enhance tx queue priority management
In busy environments, especially for ROUTER_LATE role, tx queue
fills very quickly. Delayed packets became late but new packets
to be retransmitted won't be put into the tx queue as old ones
stay there for a very long time (even a minute or more). This change
makes meshtastic prioritize new packets over late packets from tx queue
and allows to remove late packet from back of tx queue when there
is no space for a new one.
* apply copilot recommendation for cast
