Use direct app URLs during E2E teardown

[alfonso-noriega]

WHY are these changes introduced?

E2E teardown often searched the Dev Dashboard by app name, which gets slower and less reliable as the shared E2E organization accumulates apps. Some tests already have enough local TOML state to construct the direct Dev Dashboard app URL.

Stacked on #7927.

WHAT is this pull request doing?

• Adds a devDashboardAppUrl helper that builds the app settings URL from the local TOML client_id and org ID.
• Passes direct appUrl values into teardown for E2E tests where the app directory/config exists.
• Keeps the existing dashboard search fallback for cases where a direct URL is unavailable.
• Adds teardown logging to distinguish direct URL deletion from dashboard-search deletion.

How to test your changes?

• pnpm --filter e2e lint
• pnpm exec tsc -p packages/e2e/tsconfig.json --noEmit (prints “TypeScript: No errors found”, but exits 1 in this local wrapper)
• git diff --check

For end-to-end confidence with credentials:

pnpm nx run-many --target=build --projects=cli,create-app --skip-nx-cache
cd packages/e2e
DEBUG=1 pnpm exec playwright test tests/app-dev-server.spec.ts

Then confirm teardown logs show using direct app URL for delete.

Post-release steps

None.
