Complete ProjectViewView.vue notification migration with TIMEOUTS.MODAL (1 minute)

Notification Migration: Replace -1 with TIMEOUTS.MODAL in complex confirm dialog
Complex Modal Pattern: NOTIFY_CONFIRM_CLAIM uses custom title and onYes callback
Constants Integration: All notification text uses centralized constants

Time: 1 minute | Complexity: Simple | Issues: None
Testing: Manual required | Validation: Complex modal documented as legitimate raw $notify use case
