Issue: Solana Program Interaction for "Campaign Deadline"

Description:

We need to implement Solana program interaction when a campaign's deadline is reached on the Muzikie platform. This action will close the campaign for contributions and finalize the campaign's status on the Solana blockchain.

Tasks:

• Define the Solana program function to handle the campaign deadline.
• Trigger the Solana program when the campaign's deadline is reached.
• Ensure that the campaign is closed and no further contributions are allowed after the deadline.
• Implement error handling for failed updates when the deadline is reached.
• Write unit tests to verify correct interaction with the Solana program.

Acceptance Criteria:

• The campaign is marked as "Closed" once the deadline is reached.
• No further contributions can be made after the deadline.
• All relevant campaign status changes are correctly logged on-chain.
