fix: card-overview subtext wrap + v16 default bumps + chat-colour preset

UI:
- SettingsOverview cards now wrap subtext to two lines (DrawList wrap-
  width) and the card height grew from 96 to 110 px. Single-line
  fitting clipped most of the bilingual subtitles.
- HellionStyle pushes ChildBg with alpha 0 when WindowOpacity < 1.0
  to keep stacked BeginChild layers from compounding the deckgrade
  past what the slider suggests.
- WindowOpacity slider helpmarker now points to Dalamud's per-window
  hamburger menu for opacity / blur / pin / click-through overrides.

UX defaults (v15 → v16 migration adopts new values only when the user
is still on the previous default — bool flips are heuristic, the prior
defaults are from the v1.2.0 cycle and rarely toggled):
- UseCompactDensity false → true (single-line message style is cleaner)
- HideInNewGamePlusMenu false → true (consistent with other hide-flags)
- HideSameTimestamps false → true (cleaner log)
- MaxLinesToRender 5000 → 2500 (mid-range hardware friendlier)
- ChatColours empty → Hellion brand preset (the first-run wizard does
  not offer a preset choice, so fresh installs get the brand colours
  out of the box)
