Summary

Prettier configuration + Tailwind plugin
  -> format supported files changed by #161
  -> ignore generated Zod models

Adds yarn format to format the repository.

Evidence

• Before: Files from Feat/app monitoring history #161 did not consistently follow the requested configuration.
• After: Prettier check passes for supported files from Feat/app monitoring history #161; cluster and monitoring unit tests pass (10 tests). git diff --check passes.

Merge Danger

Door: two-way

Blast Radius: repository

Formatting changes cover files from #161; SQL and Prisma files have no built-in Prettier parser.
