fix(korrespondenz): scale up strip rows to readable sizes

Spec measurements (7px/8px/9px text) were spec-document zoom artifacts — not
viable at real browser scale. Updated to readable compact sizes:
- Row 1 compact label: text-xs (12px) uppercase instead of 7px
- Row 1 input: h-9 text-sm (36px/14px) instead of 30px/9px
- Row 1 swap button: h-9 w-9 to align with taller inputs
- Row 2 date inputs: h-8 text-xs (32px/12px) instead of 22px/8px
- Row 2 label/count/sort: text-xs instead of 7px/8px
