Apply configured default profile in doctor's config resolution

resolveConfig now checks for [__settings__].default_profile when no
explicit profile is set via --profile flag or DATABRICKS_CONFIG_PROFILE.
This mirrors the resolution logic in cmd/root/auth.go so users who rely
on `databricks auth switch` see the correct profile in doctor output.
