Agent review findings from PR #179:
1. static/ui.js line 542: extra } in ternary produced malformed HTML
in message bubble div (''}} instead of ''}). Caused a literal }
character to appear in the DOM.
2. api/routes.py: LOGIN_INVALID_PW and LOGIN_CONN_FAILED were inserted
into JS string context without JS-string escaping. Added backslash
escaping for ' and \ characters. Currently safe because locale values
are hardcoded, but this prevents breakage if custom locale strings
contain single quotes.
