Let the laptop say what it is doing: battery percentage, the lid, a fingerprint

Three surfaces the first laptop install showed were missing.

The bar's battery icon gets an optional exact number beside it -- GNOME's
"Show Battery Percentage", off by default for GNOME's reason, one color with
the icon so it reads as one indicator.

The Power page says what closing the lid does. The policy already existed
(LidPolicy holds a suspend inhibitor while an external display is connected)
but was surfaced nowhere, so the machine's most physical behavior was
undiscoverable -- and the deliberate absence of an override deserves stating
rather than leaving someone to hunt for a switch that does not exist.

And the Users page grows a Fingerprint card, because fingerprint login is two
systems that fail silently when they disagree: fprintd holds the enrolled
prints, authselect decides whether PAM ever asks the reader. This machine
arrived with a finger enrolled from its GNOME days and with-fingerprint off,
which reads as "the reader is broken". The card shows both facts, flips the
authselect feature through polkit with a stated reason, and hands enrollment
to GNOME's Users panel, which owns the only good capture dialog -- a named
exception in the handoff contract. Everything through scripts/panama-fingerprint,
pinned by a stub-driven contract.
