#55 Expose page zoom in Settings

[Anonymous]

Originally created by: kristofferR

Zoom exists (Cmd+-/=/0, persisted in localStorage) but is invisible in the Settings window. Add a zoom control under Settings, synced to the page via the existing `window.CARRIER_SETTINGS` / `carrier:settings` push.

Done in [#63]: Page zoom select in Settings → General, two-way synced with the keyboard/menu zoom via a sanitized carrier:zoom event, clamped 30–200, with a one-time migration of the old localStorage-only zoom.
