Add Trigger.dev V4 template

[eonminion]

Tried the existed v3 template, was not able to get it to work, so I made the new template base of the official guide:
https://trigger.dev/docs/self-hosting/docker#setup

There is problems remain unresolved:
Problem 1: Domain/URL not accessible when deploying via template

When I deploy directly using my template, the domain URL fails to open
However, when I manually copy the same docker-compose.yml and .env files into a new compose service and manually configure the domain, it works perfectly
This suggests the template deployment process isn't handling the domain configuration correctly

Problem 2: PostgreSQL username configuration error

When I try to change the PostgreSQL username (from the default), I get this error:

Fatal: role "postgresql" does not exist

It appears the system is still looking for a role named "postgresql" instead of using my custom username
