feat: rewrite InitiativeCard to single-row compact layout with tests

Replaces the two-row card layout with a single horizontal flex row that
fits within 48-56px height. Adds project badge overflow (max 2 + chip),
hover-reveal menu (opacity-0/group-hover), phase counter (X / Y),
active phase name with separator, and StatusDot pulse behavior.

Removes ProgressBar, status label text, and second row entirely.
Adds Vitest unit tests covering all 6 test groups from the spec.
