The settings list now has the account card on top, title-case group
labels and 56 dp rows that show each pane's current value. About and
"About & Data" were one placeholder page with a letter logo, a fixed
name and a store link that pointed at GitHub releases.
- About: the real logo, the app name from app.config.js, the update
state, a source link that a build can set with SOURCE_CODE_URL, and
rows for the server, update checks (Android), open-source licences,
privacy and a prefilled GitHub issue. iPhone updates link TestFlight.
- Storage & backup: usage card, offline mail, settings export/import
and reset, and a Troubleshooting page for refresh and debug logging.
- Sender favicons moved to Appearance, like the webmail.
- The S/MIME and Plugins stub pages are gone; both are webmail plugins.
The licence list is generated by `scripts/generate-licences.mjs`.
