[codex] dispatch crypto getFips callable exports

[andrewtdiz]

Refs #3955.

Summary

• route the stdlib crypto native dispatcher's getFips callable export to Node's default non-FIPS value 0
• cover the dispatcher path used by named imports and detached callable exports with a focused unit test

Why

Direct crypto.getFips() already lowers statically to 0, but callable export dispatch did not have a getFips arm. That made import { getFips } from "node:crypto"; getFips() diverge from Node's default FIPS-disabled behavior.
