[BUG] - Hide Prompt From Public Page If Not Funded

[marclupanc]

Description
Currently, when a user creates a prompt, it is immediately visible to everyone. However, users should only be able to create entries for prompts that have been funded. To prevent non-funded prompts from cluttering the search results, only funded prompts should be displayed on the search page.

Acceptance Criteria

• A newly created prompt should remain hidden until it is funded.
• Only funded prompts should be included in the search page results and in prompt creation modal.
• Ensure the funding status is checked before displaying the prompt.

Notes
If a prompt is created but not funded, it should still be stored but not publicly visible in search.
Consider adding an indicator in the user's profile for "pending" (unfunded) prompts.
