chore(config): quiet per-file reconcile output, drop backup note

The config reconcile pass printed one 'Reconciled config: <name>  (backup:
.<name>.bak)' line per changed file. Drop the per-file message entirely:
the intro notice and the two per-section '...completed.' confirmations are
enough, and the backup mention added noise. The hidden .<file>.bak sibling
is still written for safety — it's just no longer announced.
