prefs: move led_brightness after wifi_pwd; enable PWM in board.conf

Browse Source 
led_brightness sat at companion offset 174, in front of the WiFi
fields, so a 272-byte file written by upstream dev decoded with the
wrong led_brightness and a shifted SSID. Append it after wifi_pwd
(offset 272) and restore the original test offsets and the 208/272
historical lengths.

WT2 and V4.3 only got CONFIG_PWM through esp32s3_pwm_led.conf, which
the release build never passes, so release links would fail. Set
CONFIG_PWM=y in each board.conf instead. board.conf is app-only and
mcuboot does not inherit it, so the mcuboot link failure that rules out
the defconfig does not apply.
