test(#240): add component tests for all four Mission Control Strip components

17 tests across SegmentationColumn, TranscriptionColumn, ReadyColumn,
MissionControlStrip. Covers document list rendering, per-column empty
states, weekly pulse visibility, link hrefs, progress bar, and the
reviewedPct denominator (annotationCount, not textedBlockCount).
