Create campaign page redesign

[KavikaPalletenne]

TLDR: Change the flow of this page.

This should be the new flow:

1. Only show this stuff first, and a create button. No tabs for roles & review.

2. When you create a campaign on this page, it should default to not published. Then in the /organisation/{organisation_id}/campaign/{campaign_id}/edit page, there should be another tab called "Review" and a "Publish" button.

3. After backend returns a successful creation message with new campaign id, redirect to a /organisation/{organisation_id}/campaign/{campaign_id}/edit page that will contain sections (different tabs) for roles & questions (not the same tab for both like currently). We need two tabs like this:

4. For the roles section, it should support inputs for all variables in the RoleUpdate struct in the backend.

5. For the questions section, look at Peter's form creation component under /frontend/src/pages/create_question/index.tsx. For each of the roles + "General", create tabs within this section, and add a question editor component. So you will have Tab for Questions -> Tab for the Role -> question creation component. You might need to update component/backend to accept the format. Format of new questions that the backend understands:

{
    "title": "What languages do you know?",
    "description": "This is important",
    "common": true,
    "roles": [123123123, 123456],
    "required": true
    "question_type": "MultiChoice",
    "data": {
        "options": [
            {
                "id": JUST DO SOME ARBITRARY NUMBER LIKE 1,
                "display_order": 1,
                "text": "Rust"
            },
            {
                "id": JUST DO SOME ARBITRARY NUMBER LIKE 1,
                "display_order": 2,
                "text": "JavaScript"
            }
        ]
    }
}

NOTES:

• Don't worry about attaching questions to multiple roles.
• Send each question one at a time when they click "Save" button at bottom.
• Make sure you add loading states for buttons with lockouts. Add asterisks for mandatory inputs (only input without one will be role description)

By Kavika:

• Roles input should have description input field

• Roles input should now have Data Table (https://ui.shadcn.com/docs/components/data-table) and a plus button to add roles (like shadcn dialog box)

• For each roles in the questions tab, we should have different state of Peter's component and
  = General questions shud show general questions
  = Role specific qns shud only show role specific questions

• I believe Save button should be allocated to different componennt states euqually

• We should add a button for editing campaigns (so bring them back to the editing page for roles, questions)
