Admit intents with full slot validity and schema-typed slots

Why: F09 - invalid slot information was dropped at the gate, the router
saw only Start, and the command entrance passed untyped text, so
invalid-slot recognitions could still reach business execution paths.
Evidence: intentgate/route/server tests pass (verify-u6.json);
admission regression cases added.
Impact: invalid or missing slots never start executable actions;
clarification flows unchanged; cmdbus confirmation untouched.
