- mail/MailAccountSettingsSheet: handleSaveTitle + handleSavePassword now
dismiss sheet FIRST, then trigger parent SuccessAlert via setTimeout(350ms).
Fixes iOS "already presenting" crash + page-freeze when editing mailbox name.
Also fixes double-click-needed UX bug.
- stores/auth: signOut adds WebBrowser.coolDownAsync() to clear OAuth cookies.
signInWithOAuth for Google adds prompt=select_account — forces account-picker
on every sign-in attempt instead of auto-reusing previous account.
- app/(app)/index: feed page uses colors.groupedBg instead of colors.bg —
matches iOS Mail/Messages list-style, post-cards stand out clearer.
