Add RAK WisMesh Repeater Mini V2 and HP variants (#10918)

Browse Source 
* fix(esp32): skip RTC timer wake on user shutdown

Do not arm esp_sleep_enable_timer_wakeup when msecToWake is portMAX_DELAY (UI shutdown), matching nRF52 system_off semantics.

fix(rak_wismesh_tap_v2): Tag OCV curve and 16MB partition

Add OCV_ARRAY matching WisMesh Tag for accurate SOC. Use 16MB flash partition scheme for TAP V2 hardware.

* Trunkt

* Add RAK WisMesh Repeater Mini V2 and HP variants
Introduce rak_wismesh_repeater_mini (RAK4631) and
rak_wismesh_repeater_mini_hp (RAK3401) with low-VDD System OFF.
Skip LPCOMP battery wake on user-initiated shutdown to avoid
immediate reboot near the LPCOMP threshold; keep LPCOMP for
brownout-driven shutdown via variant_enableBatteryLpcompWake.

* docs(variants): update RAK BOM numbers for Repeater Mini V2 & HP

* chore: run trunk fmt
