Polish UI: consistent icon buttons, tooltips, modal backdrop close, and top bar layout

- Standardize icon button sizing (size="icon") and color (text-muted-foreground) across top and bottom bars
- Group bottom bar icon buttons with gap-0 to match top bar style
- Add missing tooltips/aria-labels for stat block viewer, bulk import buttons
- Replace Settings icon with Library for source manager
- Make step forward/back buttons use primary (solid) variant
- Move round badge next to combatant name in center of top bar
- Close player create/edit and management modals on backdrop click
