Adds two integration suites covering reconciliation rulings that the existing
crewing tests left on the happy path only:
- leave-clash.test.ts (R6/A5, §5.3): the cover-subtraction and date-overlap
paths in leaveCausesClash — a same-rank crew already on an *overlapping*
approved leave is not available cover (auto-raises), a non-overlapping leave
still counts (no raise), different-rank crew never count, and a configured
minStrength still met after the leave does not raise.
- crewing-gates.test.ts: salary/selection *returns* are Manager-only and
audited (R8); an interview waiver can never reach a NEW candidate by any path,
incl. the Manager (R2); bank reject requires remarks; PPE / next-of-kin verify
gates are MPO-only with remarks on reject (R11/§8.11); and a SUBMITTED
appraisal cannot be Manager-approved without MPO verification (H3).
Full suite: 245 unit + 225 integration green.
