feat(services): add current_active_wm_class tracking and signal, fix default active app name

- New Features
  - Added `current_active_wm_class_changed` signal and `current_active_wm_class` read‑write property.
  - Implemented setter that emits the signal when the value changes.
  - Initialized `_current_active_wm_class` and integrated it into active window updates.
- Enhancements
  - Extended active window handling to include window class information.
- Bug Fixes
  - Corrected default active application name from "Hyprland" to "Finder".
