Fix tests affected by browser logs being enabled by default

Several tests were checking CLI output without filtering browser logs,
causing failures when browser logs are now enabled by default.

Applied filterBrowserLogs helper to:
- edge-configurable-runtime test (checking for generic 'error'/'warn')
- app-dir/errors test (exact output matching with stripAnsi)
- production test (counting exact matches of 'Generating static pages')
- internal-traces test (checking output length)
