feat: enable S3 video uploads and update related configurations

- Added support for self-hosted S3 video uploads with new environment variables: OPENFRAME_ENABLE_S3_VIDEO_UPLOADS and OPENFRAME_MAX_VIDEO_UPLOAD_BYTES.
- Updated .env.example and .env.docker.example to reflect new configuration options.
- Enhanced Content Security Policy to include origins for S3-compatible storage.
- Updated dependencies for AWS SDK to support new features.
- Refactored upload logic to accommodate both Bunny and S3 upload providers.
- Updated documentation to clarify the usage of direct uploads and S3 configurations.
- Closes #11
