refactor: upgrade lucia and prisma

[arrocke]

What has changed

• Upgraded lucia from v1 to v3 - overall, this simplifies out auth significantly and the code is much easier to understand
  • This upgrade removes the concept of keys - now we just have Users and Sessions
  • Added a table for invitations since keys were handling that before.
  • Added oslo dependency to do password hashing
• Upgraded prisma to v5 - this should bring some performance boosts

QA Steps

1. Run nx run db:prisma migrate dev
2. Confirm you can still log in with existing accounts
3. Invite a new user to a language
4. Invite a new user to the platform
5. Update email and password for existing user

Post-Deployment

• [x] Nothing required

Unrelate to this PR, but I saw this when signing in from an invite.

I updated a user's email, clicked the verification link, then logged back in.

I then attempted to update the user's password

MissingEmailAddressError: We can't send emails to user with id 018e1324-0c33-e9a5-8642-6a835699f649 because they are missing an email address.

The bug occurs when I try to update the password for any user.

I updated the seed file and fixed the mailer
