fix(power): #60 name-agnostic system-battery scan

Replace BAT* globs with type=Battery + !scope=Device (same filter as
nomarchy-battery-notify) in charge-limit oneshot, menu gates, Waybar
power-profile self-gate, doctor, and install chassis detection. CMB0-
style names get charge-cap and laptop modules consistently.

V3 pending: confirm on non-BAT* hardware (HARDWARE-QUEUE). Close #60.

Verified: V1 (option-docs, hardware-db-modules, battery-charge-limit VM).
