fix(server): map schedule approval errors in the experimental create route

#59457 added the experimental schedule.create route, and Schedule.create can
now fail with Permission.BlockedError or Permission.CorrectedError when a
code condition's allowlisted tools are denied or rejected at creation. Map
both to ForbiddenError so the route's error type stays within the API
contract.

Verified: bun typecheck (server, core), server test/schedule.test.ts.
