chore(ci): give the Trigger.dev upload job room for a slow image push

[waleedlatif1]

Summary

• raise the Prepare Trigger.dev job timeout from 15 to 30 minutes
• the job normally finishes in about 13 minutes; the Depot image push occasionally runs a few minutes longer, and the 15 minute cap then kills the job mid-push, leaving a TIMED_OUT deployment on Trigger.dev and no promotion
• 30 minutes matches the promote jobs' timeout in this workflow

Type of Change

• CI

Testing

Workflow-only change; verified against the last two release runs (13 min success, 15 min cut-off during the push)

Checklist

• Self-reviewed my changes
• Tests added/updated and passing

The PR appears safe to merge because it only extends the preparation window while preserving all existing deployment and freshness gates.

Summary

Increases the prepare-trigger job timeout from 15 to 30 minutes so occasional slow Trigger.dev image uploads can finish. The upload remains unpromoted until the existing image-promotion, branch-freshness, and application-cutover gates succeed.
