Enable WebID-TLS integration tests (fix self-signed cert verification loop)

Summary

In October 2019, WebID-TLS tests were disabled with describe.skip() (commit 778095ad). The authentication code still works - just the tests are skipped and CI lacks DNS setup.

Fix size: ~10 lines changed.

The Bug

// Added Oct 29, 2019 by jaxoncreed
describe.skip('ACL with WebID+TLS', function () {  // <-- this .skip

The comment says "TLS is currently broken" but the code isn't broken - the tests just need tim.localhost to resolve to 127.0.0.1.

The Fix

1. Remove 5x .skip from test/integration/acl-tls-test.mjs:

• Line 67, 134, 571, 616, 946

2. Add 4 lines to CI (.github/workflows/ci.yml):

- name: Setup hosts for TLS tests
  run: |
    echo "127.0.0.1 tim.localhost" | sudo tee -a /etc/hosts
    echo "127.0.0.1 nicola.localhost" | sudo tee -a /etc/hosts

Done.

Verification

The code works today:

• Server starts with --auth tls ✅
• Responds to requests ✅
• Test certificates match test profiles ✅
• cert:modulus in profile matches cert ✅

Why It Matters

• README still advertises --auth tls support
• Solid spec requires OIDC, doesn't forbid TLS
• Server-to-server, CLI, IoT use cases need non-browser auth
• W3C LWS working group discussing enterprise mTLS needs (LWS-UCS #40)

References

• Commit that introduced skip: 778095ad (Oct 29, 2019)
• PR where TimBL approved TLS+OIDC coexistence: #650

Start with test/integration/acl-tls-test.mjs and inspect the five describe.skip locations at lines 67, 134, 571, 616, and 946. Then read .github/workflows/ci.yml and verify how CI configures hosts. Done means the WebID-TLS integration tests run in CI with tim.localhost and nicola.localhost resolving to 127.0.0.1.
