Part of #41: the second of five `benilla-app` pieces. This one is the UI windows: chat, the NPC windows (gossip, merchant, trainer, taxi, bank, mail, auction, quest giver), the unit, party, raid and aura feeds, the action bar, bags, tooltips, macros, the spellbook, the world map and the smaller panels. Their comments are rewritten to the rule in `docs/METHOD.md`, which is what the code does and the reference fact behind it, in a line. 26,648 comment lines become 9,221.
Fixes#98.
- **The mechanical strip.** The citations that were only a private record number go first, and each edit is shown to be a pure removal.
- **Wrong facts corrected.** The rewrite corrects the comments that stated wrong facts. Among them:
- Several client addresses carried a `0x400000` slip (`UPDATE_MACROS` is `0x852460`, not `0x452460`; the macro store's globals likewise).
- `QUEST_WATCH_UPDATE` carries the quest-log row (`0x4df880` scans the log table at `0xbb71c0`), not a watch-list position.
- The stock `ChatFrame_DisplayTimePlayed` now ships, so benilla's own `/played` lines duplicate it (#194); trainer refusals are logged, not shown on the error line; the player's cast result is `SMSG_CAST_RESULT`.
- Stock FrameXML and `Blizzard_*` line citations are checked against the stock 1.12 files, and vmangos line citations against the vmangos revision nearest the one the local server runs.
- Dozens more turned up on the way: docs sitting on the wrong item, removed functions, stale counts, broken intra-doc links.
- One test comment in `ui_script/questlog_tests.rs`, which landed with #184, carried the same watch-index slip and gets the same fix.
- **Deviation labels.** "Deviation:" now marks only a choice with a reason. An unbuilt behaviour, or one whose reference side is untraced, says so plainly.
- **Verification.** Every file strips to identical code, and `cargo fmt --check` is clean. Six second readers compared every file old against new, restored the facts the rewrite had dropped, and checked each new citation against the code, the stock files, vmangos and the reference.
Behaviour differences the rewrite surfaced are filed as their own issues (#188, #204, #222 and #259 among them). The comments here state what the code does. String literals are untouched; they are #92.
