docs(vt): slice 7 ledger — owner's third live look, Buffs strip + tooltips fixed

Records this round's two owner-reported fixes (the fabricated Buffs-tab
middle strip removed; Advanced Options tooltips removed) against the
already-closed slice 7 campaign, with commit references and the
MossTank/App test-count deltas.

 ## Closeout
 - 2026-09-07 21:10 final combined re-check (E+F, both lenses): all twelve items CLOSED with failable tests, no per-frame allocation regression, the three recall tables agree pairwise, plugin references BCL + Abstractions only — MERGE-READY. **Merged into the campaign branch at `4a825c23c`.** Owner's second-look items all closed (Advanced Options bottom block gone; string settings hidden; Items tab VTank-only). Accepted, documented deviations: the Buffs extras strip centres at the 856 floor only (anchors have no "centre"); the recall combo lists "Marketplace" in place of VTank's duplicated "Fac. Hub"; dead margins on six tabs at the 984 default. Carried polish (owner: "we do that later"): strip the retired `scroll="true"` from five markup sites and make its test failable or document that unknown attributes are ignored; delete the ~20 bindings round F orphaned; cache the two Buffs row sources like every other column; two comment corrections; Meta's delete cell as an icon. Open issues from this slice: #490 part 1 (host: `StartVisible=false` + `ShowInSidePanel=false` unshowable), #491 (buff lists not consumed by `BuffPlan.Build`), #492 (Vulkan device-loss crash + shutdown re-throw), #493 (in-game meta/loot rule editors, deferred). Owner's visual gate: the merged build launched from the gate worktree for the final look.
+- 2026-09-07 owner's third live look, post-closeout: (1) "Screenshot shows options under the buffing tab circled in red. Those are made up, remove them from here" — the whole MossTank-extras middle strip fix round B item 2 added between the Buffs tab's two lists (7 category toggles, difficulty/rebuff spinners, a second Force/Stop buffing button + status, the coverage counts) is gone outright; the Buffs tab is now VTank's own exact six controls (2 labels, 2 lists, 2 "Add..." buttons), matching the Items-tab precedent from round F item 3. The underlying BuffSettings fields (seven category bools, SkillExcessOverDifficulty, RebuffWhenUnderSeconds) stay in the model/side-car and remain editable through Advanced Options (SpellDiffExcessThreshold-Buff / RebuffTimeRemainingSeconds); Force Buff / Cancel Force Buff stay on the Options tab. Twenty-two now-orphaned XML-only bindings deleted from MossTankPanel.cs (the seven Enabled/Toggle pairs, DifficultyText/Up/Down, RebuffText/Up/Down, BuffButtonText, the Buff action) — this is the "delete the ~20 bindings round F orphaned" carried-polish item from the closeout, done as part of this fix rather than separately; BuffStatus/Coverage stay since MossTankPanelTests still exercises both directly. Commit `6be555ad4`. (2) "Also still have tooltips in the advanced options, remove please" — the three tooltip= attributes mosstank-advanced.xml had grown (option list, category checklist, value field) are removed; VTank's real AdvancedOptionsView has no tooltip mechanism, only its own description readout. New whole-tree test AdvancedOptionsPopupHasNoElementWithATooltip guards against any future re-addition. Commit `617a9c221`. Both fixes' new/changed tests shown to fail first against targeted mutations (a stray toggle re-added to the Buffs group; a tooltip= reintroduced on the option list), then reverted and restored green. MossTank suite 726 -> 726 (one Fact replaced); App markup/plugin filter 262 -> 261 (item 1, one Fact removed) -> 262 (item 2, one Fact added). Full solution Release build green throughout.
