fix: Meal Plan Notes allow Submission Without Title/Note Text

[Arshad561]

What type of PR is this?

• bug

What this PR does / why we need it:

Currently, when creating a new meal planner, the user can attempt to create a meal without providing a meal recipe or title. This results in a 422 error from the server.

With this fix:

• The "Create" button will be disabled if the meal recipe or title is empty.
• This ensures a smoother user experience and prevents invalid submissions.

Special notes for your reviewer:

Please focus on the changes made to the validation logic for enabling/disabling the "Create" button and ensure that the edge cases for validation are covered.

Testing:

• Tested the meal planner form to verify that the "Create" button is only enabled when:
  • A meal recipe is selected, or
  • A meal title is entered.
• Attempted to submit invalid data (empty fields) to confirm that the button remains disabled.
