Setup endpoints for EB and optimized existing code

[SVijayB]

Description

Setup endpoints for adding, updating, deleting, and querying EB member details.

Motivation and Context

The current version of displaying EB member details in https://www.oscvitap.org/team is not dynamic.
Adding EB member details to the API helps in rendering the page easier and also adds scalability to the current website.
The API can also be used in OSC-DBot (https://github.com/SVijayB/OSC-DBot/issues/14) for getting EB details.
Apart from sending POST requests, I've set up a basic file upload form page for direct and ease of access.

This does require an update to the docs which will be worked on soon. Referencing #7.
