feat(core) add LED charging effect in hibernation.
[no changelog]
What changed, and why it matters
This commit changes the Trezor bootloader's hibernation charging indicator from a solid blue LED to a pulsing 'charging' LED effect. There is no security-relevant change visible in the diff. It is a user-experience/visual feature.
No security action required; treat as normal feature commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
In core/embed/projects/bootloader/main.c, the code inside boot_sequence() that handles the PM_BATTERY_CHARGING state now starts RGB_LED_EFFECT_CHARGING if no LED effect is already ongoing, instead of setting a static RGBLED_BLUE color. No logic affecting firmware verification, secure boot, secrets, memory protections, or authentication was modified.
