Ldap users wrong email validation

[mehdi-ra]

Bug Description

I migrated directly from n8n 1.66 to latest version (1.79.3) and we encountered a problem with LDAP users.
It seems validation for email is still applied to ldap usernames too and it keeps us from logging in with invalid email error witch comes from zod validator defined at `packages/@n8n/api-types/src/dto/auth/login-request.dto.ts

To Reproduce

• Enable ldap on older versions like 1.66
• Migrate to version 1.79.3
• Try to login using ldap user username.

Expected behavior

Ldap users should be able to use their domain username to log in and validation should be passed for email.
