refactor: prefix all third-party service names with cameleer-

Rename all Docker Compose service names, DNS hostnames, volumes,
and Traefik labels to use the cameleer- prefix for clear ownership.

Services renamed:
- postgres → cameleer-postgres
- clickhouse → cameleer-clickhouse
- logto → cameleer-logto
- traefik → cameleer-traefik

Volumes renamed:
- pgdata → cameleer-pgdata
- chdata → cameleer-chdata
- certs → cameleer-certs
- bootstrapdata → cameleer-bootstrapdata

Updated across:
- docker-compose.yml, docker-compose.dev.yml
- installer/cameleer/docker-compose.yml
- installer/install.sh, installer/install.ps1
- application.yml defaults
- DockerTenantProvisioner.java hardcoded URL
- logto-bootstrap.sh defaults
- VendorTenantServiceTest.java
- CLAUDE.md, docs/architecture.md, docs/user-manual.md
