feat(control-center): battery charge-limit as a preset toggle

Browse Source 
The "Battery Limit" entry was a raw number prompt; make it a proper
toggle picker — Off / 80% (recommended) / 90% / 60% / Custom… — writing
settings.power.batteryChargeLimit. Kept in the control-center, where the
baked rebuild-valued System Toggles live (the rofi nomarchy-menu is the
instant surface; the CC holds config values), and reachable from the menu
via System › Control Center. Base machinery (the sysfs oneshot + AC-replug
udev in power.nix) is unchanged, so it lands on the next sys-rebuild like
its siblings.

Instant-effect (no rebuild) is refiled in BACKLOG § PROPOSED as
[blocked:hw]: it needs a udev-writable threshold node, confirmable only on
a laptop with the control.

Verified: V0 (bash -n; nix flake check --no-build, green) + V1
(nomarchy-control-center package builds — the writeShellApplication
shellcheck gate passes). Session spot-check queued in HARDWARE-QUEUE.
