- Fix DID mismatch: server now stores and reads proper did🔑z6Mk... DIDs
from database instead of deriving truncated did🔑${slice(0,32)}
- Add PRF extension to WebAuthn create/get flows for client-side key derivation
- Derive DID, signing keys, encryption keys, and EOA wallet from passkey PRF
- Auto-upgrade truncated DIDs to proper format on sign-in
- Add POST /api/account/upgrade-did endpoint for DID migration
- Add 5-step educational registration wizard (identity, passkey, DID, wallet, security)
- Add email/username field to sign-in for scoped passkey selection
- Add magic link email login for external devices without passkeys
- Add POST /api/auth/magic-link and GET /magic-login verification page
- Add mintWelcomeBalance() for 5 fUSDC to new users
- Store EOA wallet address during registration when PRF available
