Description

This PR introduces a new feature for contribution pages, allowing users to customize their channel's appearance and receive crypto payments. It includes new API endpoints, frontend components, and styles to support this functionality.

Possible Issues

1. The PR introduces a large amount of new code, which may increase the complexity of the codebase and make it harder to maintain.
2. Some of the new components (e.g., CryptoPaymentWidget) are quite large and may benefit from further modularization.
3. The PR adds several new dependencies (e.g., @solana/web3.js, web3) which may increase the bundle size and introduce potential vulnerabilities if not kept up-to-date.

Security Hotspots

1. The sendPayment function in CryptoPaymentWidget.jsx handles cryptocurrency transactions. This is a critical area that should be carefully reviewed for potential vulnerabilities or edge cases that could lead to loss of funds.

2. The image_properties function in contribution_page_controller.rb processes user-uploaded images. Ensure that proper sanitization and validation are in place to prevent potential file upload vulnerabilities.

3. The new API endpoints in contribution_page_controller.rb and public_channel_controller.rb should be reviewed to ensure proper authentication and authorization checks are in place.
