agessaman 6390763c71 fix(mqtt): count failed starts and ignore bounced sessions in cf ...

connect()/reconnect() returning an error started no attempt, so no event
arrived and the failure went uncounted -- the low-heap case the counter exists
for. Counted now in a bridge-task-only start_failures, summed into cf: and
mqtt_connect_failures.

A renewal or corrected-clock bounce whose softDisconnect() times out gets its
old session's DISCONNECTED after the new attempt raised the flag. That session
is still marked connected until the handler runs, so the gate now also
requires !connected. An ignored late CONNECTED clears the flag too.

cf: no longer depends on dc being non-zero. Comments corrected for the
PSRAM-fallback stack cost and heap_largest's sampling point; the worst-case
test now models 6 slots.
