Audit: meaningful contentDescription for actionable icons (sweep)
Upgrades ~31 sites previously annotated `// decorative` to meaningful
strings where the icon is actionable. Purely decorative leading icons
retain null contentDescription per Material 3 guidance.
Focus areas:
- Selection indicators (CheckCircle vs RadioButtonUnchecked, check marks)
- Status icons (Error, Warning, CheckCircle, ErrorOutline, CloudOff, Info)
- Expand/collapse toggles (ExpandLess/ExpandMore)
- Feature inclusion indicators (Check/Close in comparison tables)
- Requirement indicators (password strength satisfied/not)
