fix(auth): sync profile email verification with auth user (#726)

* fix(auth): sync profile email verification with auth user

Repair stale profile rows where user.email_verified is true but
profile.is_email_verified is false, which blocked the LMS with the
verify-email modal while send-verification-email returned
EMAIL_IS_ALREADY_VERIFIED.

Sync on session login, account fetch, and user update; update the
modal to respect session emailVerified and self-heal on that error.

* fix(auth): never demote profile email verification on sync

Greptile: self-hosted first signup can verify profile before
user.email_verified is set. Sync now only promotes verification.

* fix(auth): promote user.email_verified when profile is verified

Self-hosted bootstrap and other flows can set profile.is_email_verified
before user.email_verified. Sync and createProfileHook now update both
tables when promoting verification.
