fix: re-register dispatcher handlers in dbt test to survive cross-file reset()

The `beforeAll` block relied on ES module import caching to register
handlers, but cached imports are no-ops — if `dispatcher.test.ts` runs
first and calls `Dispatcher.reset()`, handlers stay cleared. Call
`registerAll()` explicitly instead.
