Fix power profile race on plug/unplug events (#5898)

The udev power_supply rule fires before sysfs `online` is updated on
some laptops (notably Lenovo Yoga Pro 7 14IAH10 with USB-C charging).
The autodetect branch reads the stale value and sets the wrong profile,
so the system stays on `performance` after unplug (or vice versa).

A single plug/unplug typically fires 3-4 udev events within ~1s (ACAD +
each USB-C port). With `systemd-run --unit=omarchy-power-profile
--collect`, duplicate invocations against the same unit name can be
dropped while the first is still running, so the surviving event isn't
guaranteed to be the latest one.

This adds a 0.3s settle delay at the top of the autodetect branch only.
Explicit `ac` and `battery` invocations remain instant.

Tested on Lenovo Yoga Pro 7 14IAH10 (Intel Core Ultra 9 285H, Omarchy
3.8.1).
