fix(tubearchivist): use startup wrapper script like Docker

Move Django management commands (migrate, collectstatic, ta_envcheck,
ta_connection, ta_startup) into run.sh startup wrapper that:
- Waits up to 60s for ElasticSearch to be healthy
- Runs all init commands before starting uvicorn
- Matches Docker's run.sh approach

This fixes ta_startup failing during install because ES wasn't ready.
The commands now run at every service start with ES readiness check.
