Pull request overview

This PR introduces a new platform-specific sleep management implementation (STM32 + ESP32) with RTC/pin wake support, and updates power management usage across the app.

Changes:

• Migrates from a single utils/sleep-manager implementation to a SleepManagerBase + per-SoC sleep manager (STM/ESP) with a thin SleepManager wrapper.
• Adds STM32WL55 RTC peripheral + wakeup pin handling and wires wakeup event reporting into the application cycle.
• Updates BME280 reads to use Zephyr runtime PM and adjusts Zephyr/West configuration to support the new power/RTC features.

pm_device_runtime_get() returns a status code (and can fail). Currently the return value is ignored, which can hide runtime-PM failures and make subsequent sensor operations behave unpredictably. Consider checking the return code, logging on failure, and skipping the fetch if the device couldn't be resumed.

wkup_count is modified in an ISR and read/reset in thread context without atomic protection. The read+clear sequence can race with an interrupt increment and lose counts. Use an atomic type/operation (e.g., atomic_t + atomic_set/atomic_get or atomic_cas patterns), or briefly lock/disable interrupts around the read/reset to make this operation race-free.
