fix: stray } in message row HTML + JS-escape login locale strings

Browse Source 
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.
