test: Refine VestingSchedulerV3 settlement and testing logic

- Update test cases to reflect recent refactoring of vesting schedule mechanisms
- Remove commented-out test methods for non-existent schedule updates
- Improve settlement calculation by using total amount to vest
- Simplify vesting schedule verification in test scenarios
