feat: Enhance plugin runtime configuration and hook management

- Added `inactive_plugins` field to `RunnerReadyPayload` and `ReloadPluginResultPayload` to track plugins that are not activated due to being disabled or unmet dependencies.
- Introduced `InspectPluginConfigPayload` and `InspectPluginConfigResultPayload` for inspecting plugin configuration metadata.
- Implemented `PluginActivationStatus` enum to better represent plugin activation states.
- Updated `_activate_plugin` method to return activation status and handle inactive plugins accordingly.
- Added hooks for send service to allow modification of messages before and after sending.
- Created new runtime routes for listing hook specifications in the WebUI.
- Refactored plugin configuration handling to utilize runtime inspection for better accuracy and flexibility.
- Enhanced error handling and logging for plugin configuration operations.
