feat(deckit): settings page for deck-it, the tablet dashboard

A page under Desktop for deck-it's ~/.config/deck-it/config.toml and its
login line. deck-it now merges that file over its shipped config key by
key, so the page writes only what differs and takes its placeholders
from `deck-it defaults` rather than copying them.

- Start at login edits hypr-theme's autostart.lua at once, as the
  Autostart page does, through Autostart.js: it re-enables a commented
  deck-it line or adds `deck-it wifi --wait`; off comments them out.
- Every config key, with launchers picked from the installed apps (desktop
  ids, reorderable) and module switches built from the defaults.
- A status line polls `deck-it status` every 2s while the page is open;
  Restart runs `deck-it stop` and the login command, then reports
  "Restarted" once the server runs with a tablet tunnelled, or what it
  saw after 30s.

Shared helpers it needed: Toml.js reads plain decimals (the display
scale), Store keeps a list of numbers numeric (the workspaces), and
ChoiceSetting takes a store as Setting and BoolSetting already do.
