Fix event registration checkboxes, add API auth header, and add No Limit checkbox UI

[maernest04]

For issue #2093

Problem

1. Broken Checkboxes: Registration checkboxes were not rendering because the form builder was stripping out the answer_options for checkbox-type questions before sending them to the API.
2. Missing API Authorization: Creating events failed because the createSCEvent API call wasn't attaching the required JWT Authorization header.
3. Unintuitive Max Attendees UI: The max attendees input relied on magic numbers (leaving it blank to send -1 for unlimited attendees), which was confusing and easily broken if users typed invalid inputs.

Solution

1. Fixed Checkbox Persistence: Updated the form builder and API payload builder to properly preserve and edit answer_options for checkbox question types, exactly like we do for multiple choice and dropdowns.
2. Added Auth Header: Updated the createSCEvent function to accept and attach the JWT token as a Bearer header, and passed the token from localStorage into the call.
3. Added "No Limit" Checkbox: Replaced the max attendees magic number behavior with a dedicated "No limit" checkbox. If checked, it disables the number input and cleanly sends -1. If unchecked, frontend validation ensures the user enters a valid positive integer.

Files Changed

• src/Pages/Events/CreateEventPage.js
  • Fixed toApiRegistrationForm and updateQuestionType to include checkbox types.
  • Added frontend validation for positive integer inputs on Max Attendees.
  • Replaced max attendees UI with a clean "No limit" checkbox alongside the number input.
  • Retrieved jwtToken from localStorage to pass to the API function.
• src/Pages/Events/CreateEventFormQuestionBlock.js
  • Added checkbox to the condition that renders the editable answer options list so admins can define checkbox options.
• src/APIFunctions/SCEvents.js
  • Modified createSCEvent to accept a token argument and insert it into the Authorization header.
