ADAPTIVE TYPOGRAPHY CONFLICT FIX

Critical fixes:
- Removed invalid FontString:GetWordWrap() usage.
- Uses CanWordWrap() plus unbounded string-width checks safely.
- Fixed native font-size dropdown closure so the selected value always targets the correct dropdown.
- Removed double geometry scaling from Calendar and Loot Tracker controls.
- Dynamic task/loot rows are rebuilt before typography is reapplied.
- Button heights now return toward their baseline when font size is reduced, instead of only growing.
- Button overflow detection uses GetUnboundedStringWidth when available, avoiding false negatives caused by truncation.
- Settings and About direct-child vertical spacing are included in adaptive reflow.
- Detached Today windows remain independently configured.

The global INTERFACE FONT SIZE remains 12..28 step 2.
