Resolve issue of user coming as undefined in audit logs

[Yagnik56]

This PR address issue of user coming as undefined in audit logs.
Solution:
If user going as undefined, keep auth checker always on so if upgrad can't authenticate user it will log out user and audit logs won't get user as undefined.

You are removing the environment variable authCheck from the code base. So also remove it from the file
env.ts
env.example
env.text

Check that there is no usage of authCheck anywhere.
