Fix freeze keyframes for trimmed clips and rename "Speed->Reset" to "Speed->Reset Speed"

- Use absolute trim end when adding freeze endpoint keyframes
- Add regression coverage for freezing a right-side split clip
- Rename Speed > Reset to Speed > Reset Speed
- Update clip docs to match the new menu label
