apply() assigned the incoming mTLS certificate and key paths and set updated
unconditionally, without comparing them to what the config already held. It is
the same presence-instead-of-value mistake this branch set out to fix, one
layer down: a caller restating its own certificate paths was reported as
changing them, which trips the value-aware update-settings gate.
