NoMongo: Replace Base64 Storage with MinIO Client in OrganizationModal.tsx

[NishantSinghhhhh]

Problem
OrganizationModal.tsx currently stores images using Base64 encoding, leading to increased memory usage and slower performance.

Solution
Replace Base64 encoding with MinIO client for direct file uploads and store only file URLs.

Alternatives Considered

• Keeping Base64 (causes larger payloads).
• Using external cloud storage (MinIO provides a self-hosted alternative).

Approach

1. Remove Base64 encoding logic.
2. Implement MinIO upload for organization images.
3. Store and retrieve file URLs efficiently.

Additional Context
This update will optimize performance, reduce bandwidth usage, and improve data handling.

NOTE

1. We recently discovered a flaw in the code base where there are some XSS and CORS vulnerabilities. This occurs when the API and Admin servers run on different machines.

2. You will notice this if you configure your Admin app on your local machine to use the API running on https://test.talawa.io/graphql.

3. The errors in your browser will look like this:

   

4. As part of this issue you will need to ensure that the browser only interacts with the API through the Admin server and never with the API directly.

PTAL at the XSS and CORS vulnerabilities mentioned above that you will need to address as part of this.
