chore: update compose stacks and shared networking

- Upgrade PostgreSQL 16 -> 17
- Upgrade CockroachDB v22.2.2 -> v22.2.15
- Upgrade substrate-gateway 2.5.0 -> 2.7.0
- Rename indexer CockroachDB service from 'db' to 'cockroachdb' to
  avoid DNS collision when both stacks share a Docker network
- Add shared external network 'tfgrid_bknd' to both compose files so
  the processor can reach the indexer gateway by service name
- Update INDEXER_ENDPOINT_URL default to http://gateway:8000/graphql
  (Docker service name) instead of localhost:8888 (host port mapping)
- Remove obsolete 'version' field from both compose files
- Update production docs with shared network setup and env var changes
