/**
 * Non-throwing credit probe for background work.
 *
 * Job processors must DEFER rather than fail when a company is out of credits,
 * so they need a boolean answer. The `CREDIT_VALIDATOR` seam
 * (`common/tokens.ts`) deliberately exposes only the throwing
 * `validateCredits`, because its other consumers (HTTP controllers) want the
 * 402 to propagate. This adapts one to the other.
 *
 * Why the seam rather than injecting `CompanyService` directly: `CompanyModule`
 * declares `CompanyController`, so importing it into a processor's module
 * mounts `companies/*` into every consumer and crashes any app that replaces
 * the company foundation with its own controller (the same reasoning already
 * documented in `agents/drift/drift.module.ts`).
 *
 * Semantics:
 * - No validator bound (app never registered one) → `true`, i.e. ungated,
 *   matching the "unchanged behaviour for consumers that opt out" contract.
 * - Validator throws 402 `NO_CREDITS` → `false`, caller defers.
 * - Validator throws anything else (company lookup failed, Neo4j down, …) →
 *   RETHROWN. Those are real errors and must not be silently mistaken for an
 *   empty balance, which would defer the job forever instead of retrying it.
 * - Credits disabled (`creditCost <= 0`) → the validator is a documented no-op,
 *   so this returns `true`.
