"""Retired: client certificate columns on assets.

Revision ID: endpoints0021clientcerts
Revises: endpoints0020appfingerprints
Create Date: 2026-09-14

This revision once added client certificate columns to the core assets table.
Client certificate authentication was replaced by per-PC endpoint credentials
(0023), so the revision is kept only so databases already stamped with it
still resolve. It does nothing; 0023 drops the columns wherever an earlier
build of this revision created them.
