ZephCore T096 26182d87cf wt2: shared PWM brightness for the status LED (heartbeat/TX/flashes)
Ports the T096 "Option 1" design (single LED, get/set leds on|off
persisted + get/set leds.brightness 0-100 RAM-only) to the Wireless
Tracker V2, which has the same single-LED-multi-purpose situation
(status_led doubles as heartbeat/message-flash/shutdown-flash/TX
indicator, same as T096's P0.28).

Adds a new ledc0 PWM channel on GPIO18 (same physical pin as the
existing plain-GPIO status_led) with heartbeat-pwm-led/lora-tx-pwm-led
aliases -- the shared C++ logic (helpers/ui/ui_common.c,
adapters/board/ZephyrBoard.cpp, helpers/led_gate.c/h,
helpers/CommonCLI.cpp) already existed from the T096 commits and needed
no changes, being board-agnostic behind DT_NODE_EXISTS checks.

CONFIG_PWM=y deliberately NOT in the board defconfig: WT2 builds via
--sysbuild (mcuboot + app as two images sharing that defconfig), and
mcuboot's minimal kernel config has no k_sem_give()/k_sem_take(), which
the ESP32 PWM LED driver needs -- CONFIG_PWM=y there links the app image
fine but fails mcuboot's link. New boards/common/esp32s3_pwm_led.conf
scopes it to the app image only via EXTRA_CONF_FILE, alongside the
existing esp32s3_usb.conf.
