Add form to create campaign (call API)

[joelpeace48-cell]

Add a form (name, description, reward per action) that submits to POST /api/campaigns and then refetches or redirects to the new campaign.

I would like to work on this issue because a simple, well-integrated form for creating campaigns will improve user workflow and reduce friction when adding new campaigns.

I’ll implement a form with fields for name, description, and reward per action, handle submission to POST /api/campaigns, and ensure the UI either refetches the campaign list or redirects to the newly created campaign. Proper validation, error handling, and responsive UX will be included.

Can deliver within the expected timeframe.

Thanks!
