Previously we had to create a separate API key to give access to chrome
extension so we can make calls to the DB. This PR includes logic to
initiate a oauth flow with PKCE method which redirects to the
`Authorise` screen to give access to server tokens.
Implemented in this PR-
1. make `redirectUrl` a non-nullable parameter
2. Add `NODE_ENV` to environment variable service
3. new env variable `CHROME_EXTENSION_REDIRECT_URL` on server side
4. strict checks for redirectUrl
5. try catch blocks on utils db query methods
6. refactor Apollo Client to handle `unauthorized` condition
7. input field to enter server url (for self-hosting)
8. state to show user if its already connected
9. show error if oauth flow is cancelled by user
