the interface labels announce their writes, and the idle tick goes quiet

- a text write names its own label, so the per-frame measure sweep drains a short ledger instead of hashing every font string twice — ~0.3 ms a frame at the Stormwind gates, gone
- the idle interface tick stops re-writing settled state: buff durations and the weapon-enchant frame write only on change, and the fade and unit-popup drivers park until woken
- the interface extract skips a hidden region before cloning its row, not after
- WOW_UPLOAD_BUDGET=<MB> brackets the arrival burst's upload pacing — a lever for measuring world entry, not a fix yet
