⚙️ FEATURE-#20: Dedupe Email.from_email / EmailFactories.from_address

[FernandoCelmer]

Closes #20

Summary

Email.from_email and EmailFactories.from_address were both calling resolve_imap_host and packing the result manually — two sources of truth for the same operation.

This PR keeps EmailFactories.from_address as the single implementation and reroutes Email.from_email through it.

Diff

@classmethod
def from_email(cls, address: str, password: str) -> Email:
    creds = EmailFactories.from_address(address, password)
    return cls(
        server=creds.server,
        user=creds.user,
        password=creds.password,
        port=creds.port,
        ssl=creds.ssl,
    )

Top-level import of resolve_imap_host in email.py is removed (no longer needed).

Test fix

tests/test_email.py::TestFromEmail::test_uses_resolver now patches email_profile.factories.resolve_imap_host (the real call site) instead of email_profile.email.resolve_imap_host.
