fix(ui): retail tooltip rendering — formula-first compose and the two-pass sizing every tooltip was missing

Two corrections from the owner's retail-render oracle at the CA5 re-check,
both against readings the TS-85 register row had recorded as settled:

Compose (skill tooltips): retail is formula + newline + description —
GetTooltip @0x004f1fe0's operator+ has the InqSkillFormula output as the
LEFT operand; the old '"\n" + formula, no separator' reading had the
operand order backwards and produced a leading blank line with the formula
and description glued on one line. A formula-less skill (Salvaging) shows
the bare description, matching the failed-InqSkillFormula branch.

Sizing (ALL tooltips, per the owner's direction): retail sizes a tooltip
in TWO passes (StartTooltip @0x0045DE90) — measure-wrap at the max width,
resize the root through the authored ResizeTo clamps, then
RecalculateGlyphList RE-WRAPS the text at its final clamped width and a
second resize grows the root's HEIGHT for the extra lines. The branch the
register called 'a structural no-op' IS that second pass; without it a
description longer than the clamped popup stayed one clipped line, where
retail shows three. ApplyTooltipText now ports the full chain, so every
tooltip surface (items, options rows, character panel, world hover, map)
wraps and grows exactly as retail.

Pinned by BuildTooltip_FormulaFirstThenNewlineThenDescription,
BuildTooltip_FormulaLessSkillShowsBareDescription, and
LongTooltip_RewrapsAtTheClampedPopupWidth_AndGrowsHeightForTheExtraLines.
TS-85 carries both dated corrections. Owner visual re-check owed: skill
tooltip shows formula on line one, description below, long descriptions
wrapping to three-plus lines inside the parchment. Full hermetic suite
15,332 passed / 0 failed.
