fix: Missing scheduled message chip

[jasonlaguidice]

Description

Fixes missing schedule message chip bug which showed up during the matrix SDK migration. My first pass at fixing this was a one-line change (which did work) but generated a type error during the requested post-deploy checks. I used Claude to investigate the errors and it added the remaining changes which fix all type errors.

Deployed in my test environment and the scheduled message feature is fully working as expected again.
