fix(ci): re-enable docker-compose integration test triggers

Restore pull_request and push triggers for the Integration Test
[Docker Compose] workflow that were removed in commit 0e3a669.

The workflow now runs on:
- Pull requests to main (excluding website/** and **.md)
- Pushes to main (excluding website/** and **.md)
- Manual workflow_dispatch triggers

This ensures the docker-compose integration test runs automatically
for all PRs, catching issues before merge. The test now passes with
the fallback logic in quickstart.sh that handles gated model failures.
