Preserve accepted messages for paused recipients (#16679)

Keep accepted deferred requests pending while their recipient is paused and deliver through normal gates after resume. Preserve company, task hold, and cleanup checks.

Verification: 247 focused checks, recursive typecheck, the full CI test and build matrix, and Apex 5/5. The local Git fixture initial-branch limitation is documented in the PR.
