fix(bb_ota_push): yield in receive loop so single-core OTA doesn't trip the WDT (#325)

The OTA push receive+write loop ran without yielding, so on single-core
targets (ESP32-S2/C3) the httpd worker monopolized the core for the whole
transfer and the task watchdog tripped the IDLE task — the extended WDT
timeout only delayed the reset, it did not prevent it. Add a vTaskDelay(1)
per ~4 KB chunk so the IDLE task and the WiFi/lwIP stack get CPU during the
transfer; it also lets the TCP window refill.

Validated on an esp32-s2-mini: a 1 MB OTA push that previously hung ~150s and
reset with reason task_wdt now completes in ~18s with a clean software reboot.
