ci(trigger): auto-deploy Trigger.dev tasks to dev-sim on dev pushes

Add a deploy-trigger-dev job that runs `trigger.dev deploy --env preview
--branch dev-sim` on pushes to the dev branch, replacing the manual step.
Gated after migrate-dev for the same reason as build-dev: the new task
code runs against the dev DB, so the schema must be pushed first.

Uses Trigger.dev's remote build (no --local-build), so the runner needs
no Docker/buildx. Requires a TRIGGER_ACCESS_TOKEN repo secret.
