Multiple issues observed in the Follow-up module related to validation, submission, and button behavior:

1. Follow-up Date Validation Missing:

• System not not submitting form when follow up date is same as Last follow up date not showing error.
• No validation error message is displayed.

      2. Submit Button Behavior Issue (Post Completion):

• After completing full 6-month follow-up cycle, Submit button remains visible and active.
• It should be disabled or hidden to prevent duplicate/invalid entries.

Steps to Reproduce:

1. Open a confirmed TB beneficiary.
2. Navigate to Follow-up module.
3. Enter follow-up date same as last follow-up date.
4. Fill remaining details and click Submit.
5. Observe submission behavior.
6. Complete follow-ups up to 6 months.
7. Check Submit button visibility.

Expected Result:

• Follow-up date should be strictly greater than last follow-up date.
• Proper validation error should be shown for invalid date.
• Form should submit successfully when all fields are valid.
• Submit button should be disabled/hidden after completing 6-month follow-up cycle.

Actual Result:

• No validation shown for invalid follow-up date.
• Form is not getting submitted.
• No error message displayed.
• Submit button remains active even after completion.
