Revert ToolCallbackConfig back to ToolCallback for consistency with Spring AI naming conventions

- Revert internal class name from ToolCallbackConfig back to ToolCallback
- Revert field name from toolCallbackConfig back to toolCallback
- Revert getter/setter methods to match original naming
- Revert configuration property path from .tool-callback back to .toolcallback
- Update all related test files to use original configuration property names
- All tests pass and functionality remains intact

This change aligns with Spring AI project's naming conventions where Properties
internal classes use descriptive names rather than Config suffixes.
