settings: tabbed panel, date format, update controls

The flat settings list had grown to 14 fields plus footer buttons —
split it into General / Format / Data / Updates tabs (same pill style
as the pinned-doc sidebar, active tab gets the selection color).

Wired the date-format setting into the engine, and reworked update
checks per an actual bug report: a boot-only check is easy to miss on
a tray app that can run for weeks without a cold restart, and every
failure was swallowed silently with no logging at all. Now: failures
are logged (console.warn) and successful "no update" checks say why
(console.info, current version vs. latest published release) so the
next report has something to go on; checks also rerun every 6 hours;
Settings has both a manual "Check for updates" button (reports back
via toast) and a toggle to turn automatic checking off entirely —
manual checks keep working either way.
