Title

test: more robust e2e tests for deployed envs

Description

• Fixes some e2e tests so they're less finicky,
• updates playwright project to support more endpoints
• Disables "relative page links" hook in webpack, so first-hits will go to /ipfs-sw-*.{css|js} instead of /ipfs/ipfs-sw-*.{css|js}

cc @aschmahmann. FYI that "allows users to load HTML page via filesystem in browser" that was added a long time ago is now unsupported. We can look into enabling later once we get our ideal envs working consistently.
