Apply CurvePreferences in the central TLS argument builder.

cmd/main.go assigns profile.Groups to CurvePreferences, but BuildTLSArgsFromClusterTLSProfile does not consume that field. The server, repo-server, and image-updater paths all use this builder, so configured groups are discarded and these components use their default curve preferences. Add the consumer-side handling in the central builder; this is separate from Apache groups output.

Review comment at @cmd/main.go at line 390:
Update BuildTLSArgsFromClusterTLSProfile to consume CurvePreferences and include
the configured groups in the generated TLS arguments, so all components using
this builder honor the profile settings. Keep this change in the central TLS
argument builder, separate from Apache groups output.

After applying the fix, consider running `coderabbit review --agent` for local
