* fix(native): implement BinarySemaphorePosix with proper pthread synchronization
The BinarySemaphorePosix class (used on all Linux/portduino/native builds)
had stub implementations: give() was a no-op and take() just called
delay(msec) and returned false. This broke the cooperative thread scheduler
on native platforms — threads could not wake the main loop, radio RX
interrupts were missed, and telemetry never transmitted over the mesh.
Replace the stubs with a proper binary semaphore using pthread_mutex_t +
pthread_cond_t + bool signaled:
- take(msec): pthread_cond_timedwait with CLOCK_REALTIME timeout, consumes
signal atomically (binary semaphore semantics)
- give(): sets signaled=true, signals condition variable
- giveFromISR(): delegates to give(), sets pxHigherPriorityTaskWoken
Tested on Raspberry Pi 3 Model B (ARM64, Debian Bookworm) with Adafruit
LoRa Radio Bonnet (SX1276). Before fix: no radio TX/RX, no telemetry on
mesh. After fix: bidirectional LoRa, MQTT gateway, telemetry all working.

This reverts commit 391928ed08.
Since esp32_https_server commit e2c9f98, this is no longer necessary.
Also, the esp32-common.ini '-include mbedtls/error.h' causes a build error
under IDF v5 (https://github.com/meshtastic/firmware/pull/9122#issuecomment-4185767085):
<command-line>: fatal error: mbedtls/error.h: No such file or directory
so this change fixes that error.
* Add powerlimits to reconfigured radio settings as well as init settings.
* Refactor preamble length handling for wide LoRa configurations
* Moved the preamble setting to the main class and made the references static
MQTT password was logged in cleartext via LOG_INFO when connecting to
the broker, exposing credentials to anyone with log access. Replace
the password format specifier with a static mask.

SerialModule's weather station parser divides by velCount and dirCount
to compute wind speed/direction averages. Both counters are only
incremented when their respective sensor readings arrive, but the
division runs whenever gotwind is true (set by EITHER reading) and
the averaging interval has elapsed.
If only WindDir arrives without WindSpeed (or vice versa), or if the
timer fires before any readings accumulate, the division produces
undefined behavior (floating-point divide by zero on embedded = NaN
or hardware fault depending on platform).
Fix: add velCount > 0 && dirCount > 0 guard to the averaging block.
