feat: add branded login.html with PAM/password mode detection
- Create muxplex/frontend/login.html with: - POST form targeting /login with password autocomplete='current-password' - Wordmark img referencing /wordmark-on-dark.svg - Hidden username field shown in PAM mode via window.MUXPLEX_AUTH - Error banner shown when ?error=1 query param is present - Inline dark-theme CSS with design token variables (--bg, --accent, etc.) - Inline <script> reading window.MUXPLEX_AUTH for auth mode detection - Add 6 login tests to muxplex/tests/test_frontend_html.py: - test_login_html_exists - test_login_html_has_form - test_login_html_has_password_autocomplete - test_login_html_has_wordmark - test_login_html_references_muxplex_auth - test_login_html_has_error_display All 6 tests pass. Existing 15 index.html tests unaffected. Co-authored-by: Amplifier <amplifier@amplified.dev>
