amosblomqvist 5e21561997 Settings-dialog round 1b: un-double the section inset
The dialog's content wrapper added px-6 py-5 ON TOP of SettingsSection's
own padding (48px horizontal, 81px top — measured live). The wrapper is
now bare; the section component owns its rhythm, and the loading/error
states carry their own padding. Section box now spans the scroll column
(61px from the dialog top = the 60px header band), text inset 24px.

Gates: typecheck, lint, 701/701.

/**
* THE SETTINGS DIALOG (settings-app wave, 2026-09-20): the thin settings
* page graduated into the designed surface — a centered modal over
* everything, left section nav + one scrolling content column.
*
* Owner decisions this wave:
* - Dialog, not a page: opens over whatever screen you're on (the payoff:
* appearance edits restyle the chat LIVE behind the dialog). Escape,
* backdrop, and ✕ all close. Modal-only — /settings redirects, so
* nothing links into a dead surface.
* - Left section nav in the app's mono chrome (text-only, session-list
* language — active = bg-accent), no icons, matching the minimal-color
* doctrine.
* - The dialog is surface-agnostic by construction: the sections talk to
* /api/settings* and localStorage only, so this shell can be re-mounted
* as a true OS window in the Electron round with near-zero churn.
*
* The record + the single `write` seam moved here from the thin page:
* one record instance for the whole dialog, sections write through it,
* switching sections never refetches.
