Give a laptop its first week: the keys, the lid, the battery's endgame

The audit's fourth tier -- what a Framework owner reaches for in the first
week and found missing.

The power button stops being an instant, unconfirmed poweroff: a shipped
logind drop-in tells the daemon to stand down and the compositor binds the
key to the power menu, the way GNOME turns it into a question. Holding it
still hard-cuts through firmware. change-settings restarts logind so the
change applies without waiting for a boot, and the Power page says what the
button does now.

The function row fills in: F10 (XF86RFKill) toggles airplane mode through a
new panama-osd verb that blocks or unblocks every radio and says which way it
went; F9 (XF86Display) opens the Displays page, the honest action until
mirroring exists. And the lid becomes a switch bind: closing a docked lid
turns the internal panel off so nothing renders inside a closed shell and no
workspace strands on an invisible output, and opening it restores the panel
with the mode and scale chosen in Settings. panama-lid owns both decisions;
undocked machines suspend via logind before any of it matters.

The battery gets an endgame. On battery the screen dims to 30% two-thirds of
the way to blanking -- GNOME's single largest idle battery saver -- and
restores exactly the level it saved. At the urgent threshold the machine
suspends after a fifteen-second grace, cancelled by plugging in, because a
suspend preserves the session for days and a hard cut at 0% preserves
nothing; "Only warn" remains a choice on the Power page. Hibernate joins the
power menu, but only where logind answers CanHibernate with yes -- an entry
that fails silently is worse than none.

And brightness stops being two code paths: the Displays page now embeds the
same control the quick-settings panel uses, so the built-in backlight and
DDC/CI monitors share one surface that withdraws itself where neither
exists. The lid contract narrows to what its principle protects -- a
HandleLidSwitch drop-in -- so deliberate policy for other keys can ship.
