docs(wiki): regenerate Reference-Contracts.md via wiki-gen — formatting

Catches up the committed file with the @evolv/wiki-gen tool's current
canonical output (bare `any` for payload type, no backticks on `any`).
Brings HEAD in line with `wiki-gen --check` so CI doesn't trip on this
file going forward. Content semantics unchanged.
