feat: Implement Refresh Tokens

[iamareebjamal]

Fixes #6168

[iamareebjamal]

flask_jwt is abandoned. Last update was 4 years ago (2015)

pallets-eco/flask-jwt#123

Should have already shifted to flask-jwt-extended

It is configurable enough that there'll be no breaking change. But even if there is, we'll move ahead with the shifting. Worst thing that can happen is that people will be logged out, which is not bad as they already do every 24 hours
