3d day of coding

I finally managed to match the availability of a teacher with the schedule request of a student. It took some personal debugging as well as ChatGPT help to confirm my suspicion and speed up the implementation process. I made some TailWind improvements as well.

Next steps:

• Add a logout button

• List a teacher's availabilities in a list so that the student can pick them. Show calendar view if possible.

• Replace the current email login with NOSTR login. Maybe using an extension at first, but allow for more options if possible.

Can someone point me where to look to learn how to do this NOSTR login part?
