- Extracted `PasskeyTable` and `WebAuthnScript` into `ui/components/auth/`.
- Refactored `PasskeysPage.tsx` and `RegisterPage.tsx` to use the new components instead of inline scripts and HTML.
- Deleted the duplicate `ui/public/ui/utils/bip39_wordlist.ts` and `ui/public/ui/utils/bip39.ts`.
- Updated all import references to use `ui/utils/bip39_wordlist.ts` and `/public/utils/bip39.ts`.

* Added `prf_enabled` and `prf_salt` columns to the `passkeys` table.
* Updated registration API endpoints to request and store the PRF extension capability and generate a secure salt.
* Updated the login API endpoints to map stored PRF salts into the `evalByCredential` array for the WebAuthn challenge.
* Enhanced the client-side WebAuthn SDK (`auth-client.js`) to extract the PRF Base64URL string output, decode it into a `Uint8Array`, and securely derive a 256-bit AES-GCM Key Encryption Key (KEK) via `crypto.subtle.deriveKey` using the `auth-yes:prf:device-share:v1` info string.
* Implemented graceful fallbacks throughout the stack to ensure registration and standard logins proceed if PRF is unsupported.
* Added corresponding unit tests to verify PRF flow and rejection logic.
* Verified visual and functional changes for the optional username input on the login page via Playwright scripts.
