refactor(ci): rename DellMonitorControl to MonitorControl

Rename project from DellMonitorControl to MonitorControl to reflect broader monitor compatibility beyond Dell hardware. Update all references in solution file, workflow, and project paths.

Add DDC/CI rate limiting and throttling logic to prevent command failures:
- Minimum 50ms interval between commands to same monitor
- 8-second grace period after system resume before sending commands
- 3-second cooldown after timeout to allow monitor recovery
- Global semaphore to prevent command collisions

Replace old icon with new generic monitor icon (ico and png formats).
