Subject: [PATCH] test(shared): add 215 schema validation tests covering all 17
 Zod schemas

Phase 3a: raises shared schema coverage from 5.5% to ~95%. Tests cover
valid roundtrips, invalid rejection, edge cases for refinements, defaults,
date coercion, and the generateDynamicZodSchema runtime builder.
