Release commit for v0.4.1.1, a patch release with:

• Fix "Log in as guest" on the login page #26: "Log in as guest" button styled and shown only when a guest account is usable; guest login errors reported instead of swallowed
• CKEditor: fix transparent/unreadable editor with a --ck-* variable theme #27: CKEditor readable in light and dark mode (plain CSS over --ck-* variables, no build step)

Changes in this PR

• Version 0.4.1.1 in pyproject.toml, uv.lock and whiteneuron/__init__.py (release date 2026-10-21)
• CHANGELOG.md and README.md: v0.4.1.1 entry
• docs/reports/releases/2026-10-21-v0.4.1.1.md: release notes

Validation

• manage.py test whiteneuron: 75 tests pass (with SKIP_GUEST_LOGIN=True and False)
• check clean, makemigrations --check no changes, msgfmt --check ok
• bash scripts/tailwind.sh leaves styles.css unchanged
• uv build + twine check pass; the wheel installs in a clean venv and reports 0.4.1.1

After merge: tag v0.4.1.1 on the merge commit and publish the GitHub Release, which runs the PyPI and Docker base image workflows.
