Add a default-enabled password-auth feature to sqlx-postgres and expose it as postgres-password-auth through the SQLx facade, macros, and CLI. This preserves existing behavior while allowing certificate-only users to omit the cleartext, MD5, and SCRAM authentication code and dependencies. Return a configuration error when a password authentication method is requested without the feature. Update CI, examples, tooling, and documentation so password-backed configurations enable it explicitly and certificate-only coverage exercises the reduced build. Closes transact-rs#4416.

Does your PR solve an issue?
Fixes #4416.
Is this a breaking change?
Potentially. Public APIs remain unchanged, and default-feature users retain password authentication.
Users with
default-features = falsewho rely on PostgreSQL cleartext, MD5, or SCRAM authentication must enablepostgres-password-auth. Certificate-only connections can omit it.Summary
