Modified independent profile status behavior

As a student I want the modified independent status on my profile to update when a pending modified independant application is cancelled.

## Acceptance Criteria

### Basic changes

- [ ] Add new modified independant status of Requested

- [ ] When Modified Independant form is submitted and its current state is at Not Requested , change the status on the student profile to Requested.
- [ ] Change "yes" value to Approved
- [ ] Change "no" value to Declined
### Cancellation behavior
- [ ] When a student cancels a pending Modified Independant Status application form the following logic should apply:
- [ ] If status on profile = "Requested" revert to "Not Requested"
### Additional submit behavior logic
- [ ] If status = "No" or "Declined"it will automatically change to "Requested" upon new submission of the appeal

## Additional Context
- If status on profile = "Yes" for modified independent it will not change to requested so no action is required.
