[PATCH 00/16] PR: resource leak fixes and improvements

[Peddolla Harshavardhan Reddy]

These changes are specific to the Proximity Ranging (PR)
subsystem. This series fixes several resource-management
bugs and extends channel selection and session event
reporting to complete the PR flow.

It plugs pr_pasn_params memory leaks and radio work stalls
across multiple failure paths, adds retransmission for
unACKed PASN auth frames, and ensures session state is
fully cleaned up on every error and abort path.

Channel selection is improved by raising the operating
class limit, fixing 6 GHz exclusion in both NTB and EDCA
paths, adding a preferred_freq parameter to steer ranging
to a specific frequency, and preferring higher bands as a
tiebreaker.

Finally, two new control interface events — PR-PEER-FOUND
and PR-RANGING-TERMINATED — allow upper layers to track
peer discovery and session lifecycle.
