feat(P03): complete placement-reporting phase (REQ-11-003)

Phase 3 complete: the D-107 overview (distinct-learner counting
toward 1,000), the per-employer placement view, placement.ts wire
pins, the engine-client placements section, the /employer/applications
page + the overview mock-block conversion. Verify four-layers PASS.
Ships as v0.10.3.
