Pull request overview

This PR introduces a Docker-based workflow for running Playwright E2E tests (to better match CI and reduce OS-dependent snapshot diffs), updates CI workflows to use the Docker path, and adjusts formatting/tooling and a couple of E2E test waits/timeouts.

Changes:

• Add tools/e2e Dockerfile + docker-compose setup and expose it via e2e:docker scripts.
• Switch GitHub Actions E2E workflows to run tests via Docker and update snapshot approval to include *.txt artifacts.
• Update Prettier tooling (Prettier + prettier-plugin-sh) and tweak some Playwright test waits/timeouts.
