Quality of life changes for Prisma

[aaron1857]

These are some quality-of-life changes for prisma

• Update seeding to create a user using our current structure of better auth email OTPs
  • I figured this is better since that is the default for new projects
• Changed the prisma:reset command to take care of most Prisma commands in one go
  • It resets the DB, migrates pending changes, generates the client, and then seeds it with seed.ts
  • This is safe to run even when a DB or any migrations do not exist (i.e., for new projects).
• Changes schema.prisma to have a default for IDs. This is because more often than not, the ID is not important and is more of an internal thing. We might as well make Prisma generate a random one instead of doing it ourselves
  • This is only a default; you can still provide an ID when creating a new user and such if you want.
• Updated README to reflect these changes
