feat(system): enable fwupd by default; document power options

Ship `services.fwupd.enable` distro-wide (mkDefault) for firmware updates
via LVFS — the daemon + metadata-refresh timer only, no automatic
flashing, so applying an update stays an explicit `fwupdmgr update`. A
no-op where LVFS sees no devices; overridable natively. Sits with the
other mkDefault desktop services rather than a nomarchy toggle (it's a
single service, like upower).

Also documents the `nomarchy.system.power.*` options in the README table
(missed when the power module landed) and adds a short note on the
fwupd default.

Beyond the `nomarchy.*` surface, the system layer turns on the usual
desktop services with `lib.mkDefault` (override natively). One worth
calling out: **`services.fwupd.enable`** is on by default for firmware
updates via LVFS — it only refreshes metadata, never flashes on its own,
so run `fwupdmgr update` to apply. Disable with `services.fwupd.enable =
false;` on machines without real firmware (VMs/headless).
