Appeals: The "Student current year income appeal" doesn't display for dependent students

_As a dependent student_ whose annual income is not used for any assessment calculation
_I want_ the "Student current year income appeal" to **not** display on my Appeal page
_So that_ it removes the possibility of an unnecessary appeal (that does not affect my funding assessment) being submitted.

### Acceptance Criteria

- [ ] Changes required for new PY 26/27 Full-time applications.
- [ ] Remove student current year income appeal eligibility for all dependent students.
- [ ] Please identify and provide business the application numbers with pending student year income appeals.

Dependent student
- [ ] When no longer eligible for the Student Current Year Income Appeal, the appeal doesn't display.

**Additional context**
Independent student
- The Student Current Year Income Appeal continues to be displayed in accordance with the eligibility. No changes required.

**QA Notes**
- [ ] 1 – Dependent student
Given a student's dependency status is Dependent
When they navigate to the Appeals page
Then the Student Current Year Income Appeal is not displayed.

- [ ] 2 – Independent student
Given an applicant has submitted their application and accepted their funding assessment
And the applicant's dependency status is Independent
When they navigate to the Appeals page
Then the Student Current Year Income Appeal continues to be displayed in accordance with existing eligibility rules.

- [ ] 3 – No impact to other appeals
Given an applicant is eligible for other appeal types
When they access the Appeals page
Then all other appeals continue to display according to existing business rules.

- [ ] 4 - Dependent changes to Independent
Given a dependent student changes their status to independent
When making an Edit of the same application
Then the "Student current year income appeal" must display on the Appeals page for the new version of the application.

**Current behavior**
- Following submission of an application and acceptance of their funding assessment, dependent students are able to access the "Student Current Year Income Appeal" from the Appeals page.
- For dependent students, financial need is assessed using parental income, rather than the student's current year income. As a result, changes to the student's current year income do not impact the assessment of their eligible loans and grants.
- Displaying this appeal to dependent students can cause confusion and may result in applicants submitting appeals that cannot change their assessment, creating unnecessary work for StudentAid BC staff.

**Business Rule**
If the applicant's dependency status is Dependent, the Student Current Year Income Appeal must not be displayed on the Appeals page.
If the applicant's dependency status is Independent, the existing behaviour remains unchanged and the appeal continues to be displayed (subject to existing eligibility rules).
