chore: deflake joins e2e tests (#11034)

Previously, data created by other tests was also leaking into unrelated tests, causing them to fail. The new reset-db-between-tests logic added by this PR fixes this. 

Additionally, this increases playwright timeouts for CI, and adds a specific timeout override for opening a drawer, as it was incredibly slow in CI
