chore: pin apollo-mcp-server version and improve API logging configuration

- Pin `apollo-mcp-server` image to v1.7.0 and make version configurable via `APOLLO_MCP_SERVER_VERSION`.
- Refactor API logging: rename `MCP_LOG_*` variables to `VERBOSITY_*` for clarity and deprecate unsupported fields.
- Ensure v1.7.0 compatibility by updating `mcp-config.yaml` and removing obsolete fields.
- Update documentation and configuration files to reflect these changes.
