test(runtime): narrow res.response in the rewritten api-dispatch pins; test-typecheck debt re-recorded downward

The two #27506 cases in http-dispatcher.actions-type-dispatch.test.ts read
`res.response.…` unnarrowed, which grew the ledgered TS18048 debt for the
file (24 recorded, 28 measured). They now bind the envelope once and refuse
loudly when it is absent, and the pin they replaced carried two of the
ledgered accesses, so the file's debt shrinks 24 -> 22;
`gen:test-typecheck-debt` re-recorded that number (no other entry moves).
