Do we need two login views?

[zven]

I just realized that we currently have two login views:

https://staging.opensensemap.org/explore/login:

And https://staging.opensensemap.org/login

Do we need both?

I'd say thats nonsense. Lets just redirect to explore and get rid of login.tsx, keeping only `explore.login.tsx
