style: GUI polish — visibility-aware polling, CSS vars for dark mode (code-review.md § Phase 2)

Browse Source 
- panel.js: skip HTMX polling requests while the tab is hidden, via
  htmx:beforeRequest rather than htmx's eval-based trigger filter (the
  panel's CSP allows no unsafe-eval).
- panel.css: replace all dark-mode !important overrides with CSS custom
  properties reassigned once under prefers-color-scheme: dark.
- panel.css: consolidate the duplicate main{max-width} rule.
