refactor: const/let modernisation and eliminate duplicate date-parse logic

- Replace all var declarations in base.html, index.html scripts with const/let (const for bindings that are never reassigned, let otherwise) - Add _toIso() helper to links.html script block and replace the two inline .replace(' UTC','Z').replace(' ','T') patterns with it - Replace var with const in links.html _linksInterval Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
