[border-agent] process Keep Alive messages only for active commissioner (#10750)

Browse Source 
This commit updates how Keep Alive messages are handled by the Border
Agent. After establishing a secure session, a device has
`TIMEOUT_COMM_PET` (50 seconds) to take any action, including sending
a petition to become an Active Commissioner. This change ensures that
Keep Alive messages are ignored before a device becomes an Active
Commissioner, preventing candidates from extending their sessions.
Keep Alive messages are now processed only for Active Commissioners
(BA in `kStateAccepted` state), aligning the implementation with the
Thread specification.
