FastAPI path routing can't capture a slash inside a {case_number}
segment — %2F gets decoded before route matching, so any case created
with "1000/0426" becomes permanently unreachable at
GET /api/cases/{case_number}/details. Enforce the hyphen convention
used by existing prod cases (1033-25, 1130-25) at the zod layer so
the wizard rejects the bad shape before submit.
