Introduce plugin initialization phase and consolidate config handling

- Added `initialize_plugins` method to `PluginManager` for requesting and processing file system resources during plugin initialization.
- Introduced `InitializationResult` and `ResourceRequest` structures for fine-grained resource management (e.g., directories, files).
- Enhanced configuration injection by separating `global_configs`, `defaults_configs`, and backend-level `haproxy_config`.
- Updated existing plugins (e.g., JWT Validator, Cloudflare) to use the initialization phase for resource setup.
- Simplified domain plugin execution by consolidating configuration logic into unified loops.
