Gate frame delivery on getAdminAuthorized under access control (screen
pixels are operator content, same rule as mesh packets); move the drain
to lowest getFromRadio/available priority behind the replay drain; give
each PhoneAPI its own (frameId, offset) cursor via ScreenMirror::copyChunk
so coexisting BLE/serial/TCP clients each receive complete frames; disarm
and free the snapshot on client close and on setMirror(false), with
memaudit accounting and a geometry-change realloc guard; honor the
local-connection-only contract for both admin verbs (mp.from == 0);
demote the per-frame onNotify log to TRACE; hoist the guard into a
derived HAS_SCREEN_MIRROR in configuration.h.
Regenerates protos for the reviewed contract (FORMAT_UNSPECIFIED = 0,
MONO_VLSB = 1, width/height int_size:16).
