Refactor E2E tests and configuration format

- Replaced `easymapping` configuration with `containers` for better maintainability and clarity.
- Introduced `DockerComposeFixture` class in `utils.py` to manage Docker Compose lifecycle and smart build strategy.
- Enhanced YAML-to-environment variable conversion in `ContainerEnv` for dynamic configuration support.
- Updated HAProxy configurations and test fixtures to reflect the new format.
- Improved test coverage for YAML parsing, environment variable handling, and HAProxy config generation.

+:::info New Configuration Format
+The `containers` format simplifies static configuration:
+- **Flatter structure**: `"hostname:port"` keys instead of nested `easymapping` → `ports` → `hosts`
+- **Better readability**: Port and localport embedded in keys (`"host:port"` and `"container:localport"`)
+- **Plugin support**: Global and per-host plugin configuration
+- **Clearer mapping**: Format mirrors internal Docker label structure
