refactor(ble_log): move runtime dispatch to esp_timer

Browse Source 
Replace the dedicated BLE Log FreeRTOS task with a deferred esp_timer
batch dispatch. The first submission anchors a one-shot 1 ms deadline;
the callback drains the queue depth captured at entry and schedules the
next fixed defer only for arrivals left behind. Later submissions cannot
move the current deadline, and no fixed batch-size cap limits throughput.

Protect queue and timer lifetime with runtime references. Drain queued
submissions before ble_log_lbm_flush_all_trans waits for transport
ownership to return, so synchronous flush does not depend on the deferred
alarm firing.

Keep the defer alarm as a light-sleep wake source and select
ESP_TIMER_IN_IRAM. Timestamp synchronization uses the shared ESP timer task
with skipped unhandled events, so it neither wakes light sleep nor replays
missed periods. Retain legacy task and trigger symbols as hidden no-op
sdkconfig compatibility options.
