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

Rename all Docker/K8s service names, DNS hostnames, secrets, volumes,
and manifest files to use the cameleer- prefix, making it clear which
software package each container belongs to.

Services renamed:
- postgres → cameleer-postgres
- clickhouse → cameleer-clickhouse
- logto → cameleer-logto
- logto-postgresql → cameleer-logto-postgresql
- traefik (service) → cameleer-traefik
- postgres-external → cameleer-postgres-external

Secrets renamed:
- postgres-credentials → cameleer-postgres-credentials
- clickhouse-credentials → cameleer-clickhouse-credentials
- logto-credentials → cameleer-logto-credentials

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

K8s manifests renamed:
- deploy/postgres.yaml → deploy/cameleer-postgres.yaml
- deploy/clickhouse.yaml → deploy/cameleer-clickhouse.yaml
- deploy/logto.yaml → deploy/cameleer-logto.yaml
