docs: expand desktop-settings spec and add panel prototypes

I folded the home-handoff control-set decisions into the desktop-settings panel spec. The controls table gains night-light, Do Not Disturb, power profile, lock/suspend actions, scenes, and a wallpaper sub-view. Volume and theme are out of scope, with reasons, and the format pickers move to their own display-format sibling spec (stubbed). The scenes and wallpaper-shape decisions close. The spec stays DRAFT pending UI prototyping.

I added five direction prototypes over a shared engine (tile grid, sectioned rack, scenes-first, instrument cluster, expandable rows) so the layout gets picked against working behavior.

I closed the shipped Next Session Focus work in todo.org: notification loudness, clock right-click dismiss, date-only scrolling, the wired-interface indicator, and best-saved WiFi connect, plus velox boot recovery. The three design-blocked network and audio items stay TODO with their open question recorded.
