Describe this PR

• This is the final things to fix prior to new release 2024.5.0.
• Please check over all of my logic & test this thoroughly @Sujanadh @Anuj-Gupta4 @NSUWAL123 @manjitapandey
• I haven't thoroughly tested this yet, as I planned to merge early and test more easily on dev. It's also getting late for me, so I though it best to just push and let you all help me find errors too!

Content

• I removed the 'Temporary Login' card / option from the mapper frontend.
• Now the login is handled seamlessly: if the user is not logged in, they are provided a temporary token/cookie.
• If the user logs in via OSM, they overrides the temp token (temp cookies are revoked).
• We should update at some point to inform the user of this:
  • First load of mapper frontend, we have a localStorage key / prompt.
  • If the user is not signed in via OSM, we say: 'You are not signed in via OSM. If you wish for your mapping contributions to be linked to your profile, please log in first'.
• I made the logic a bit more DRY on the backend.
• The refresh endpoints refresh both cookies, but also return the user details JSON.

Merging early so this can be tested easily, but please still review + test thoroughly everyone 🙏

When I wake up, if all is well, I will make the release 🎉

On refresh, the json payload was not returning with AuthUser correctly:

Added commit 3a9a50f to address this, now deploying.

Heading to bed, but hopefully it works 🤞 😴

@spwoodcock
I tried testing and debugging the code. Findings:

The refresh endpoint for mapper worked at first.
Then I cleared all cookies and logged in.
Now the endpoint has stopped working.

If there are no tokens and mapper frontend is accessed:
Refresh mapper looks for mapper login and the authenticate user function throws error saying token not found before the refresh mapper has a chance to set temporary cookies.

Refresh management endpoint also throws error.

Since same functions are being called with different parameters and response is being passed around a lot, the generated response does not always work with other functions and frontend.
