fix: initialize databases before starting dependent services

- start postgresql first, then run init_databases.sh, then other services
- add depends_on postgres for lightrag service
- remove unused nocodb from databases list
- document database initialization in add-new-service workflow

+# List of databases to create (add new services here)
+DATABASES=(

+This script:
+- Runs automatically during install/update (BEFORE services start)
+- Creates database if it doesn't exist (idempotent)
+- Waits for PostgreSQL to be healthy first

+**Important:** Database name should match what's configured in docker-compose.yml environment variables.

+Example in docker-compose.yml:
+```yaml
