The URL parser resolves %2e%2e like .., so /{base}/assets/%2e%2e/api/...
passed assetAllowed and would load from outside the asset prefix. A
segment is now a dot segment after decoding %2e, in any case.
- tests/app/pluginAssets.test.ts covers the URL check, loadScript,
loadStyles, activateStyles and loadControllerAssets
- modules/boardwalk/dist rebuilt
