v0.92.1

Added

• Reveal and copy installer secret keys — after generating the session secret or database encryption key in the setup wizard, the value is now shown and a copy button appears, with a screen-reader-announced confirmation, so the keys can be recorded before they are saved.

Changed

• Stronger key-loss warning in the installer — the security-keys step now leads with a prominent warning that losing the keys makes encrypted data unrecoverable, echoed by a backup reminder on the final screen.
• Grouped installer advanced step — reverse proxy, single sign-on, backups, and WebDAV are now split into "Networking" and "Integrations & backups" sections, with the security-relevant reverse-proxy choice visually emphasized.
• Confirmation before the installer writes config — the irreversible "Save & Start" action now asks for a second click before writing `.env` and starting the container.
• Themed visibility toggles in the installer — show/hide controls use themed icons with pressed-state semantics instead of an emoji glyph.

Fixed

• Correct scheme for installer redirect links — generated Google/OIDC redirect URIs and the final "Open Yuvomi" link now use https or http based on the reverse-proxy choice instead of always using http.
• Installer accessibility and mobile polish — the wizard now respects reduced-motion, enlarges touch targets to 44px, keeps the footer reachable on mobile, and aligns correctly in right-to-left languages.
• Safer installer input handling — the backup cron schedule and retention count are validated, the admin step has a Back button, text fields submit on Enter, and a failed `.env` save now surfaces the actual server error.
