fix: playwright tests

[maiconcarraro]

PR Type

• Build or CI related changes

Describe the current behavior?

The existing npm run tests is using a hardcoded URL mapped to https://preview.pwabuilder.com/reportcard?site=https://webboard.app which isn't working (outdated env variable) and also doesn't help validate localhost.

Describe the new behavior?

Keep existing setup for CI, and allow localhost sanity check run for devs.
