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

[NishantSinghhhhh]

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

Solution
Replace Base64 encoding with MinIO client for direct file uploads, storing only file URLs.

Alternatives Considered

• Keeping Base64 (causes increased payload size).
• Using external cloud storage (MinIO provides a self-hosted alternative).

Approach

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

Additional Context
This update will enhance performance, reduce data transfer size, and improve storage efficiency.

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.

How's progress on this? It needs to be completed as a GSoC prerequisite.
