* fix: reduce CPU usage, fix Vegas mid-cycle refresh, and throttle high-FPS plugin ticks Web UI Info plugin was causing 90%+ CPU on RPi4 due to frequent subprocess calls and re-rendering. Fixed by: trying socket-based IP detection first (zero subprocess overhead), caching AP mode checks with 60s TTL, reducing IP refresh from 30s to 5m, caching rendered display images, and loading fonts once at init. Vegas mode was not updating the display mid-cycle because hot_swap_content() reset the scroll position to 0 on every recomposition. Now saves and restores scroll position for mid-cycle updates. High-FPS display loop was calling _tick_plugin_updates() 125x/sec with no benefit. Added throttled wrapper that limits to 1 call/sec.

The high-FPS call site passes an explicit 1.0s interval. Narrow _load_font exception handler from bare Exception to FileNotFoundError | OSError so unexpected errors surface.

Scale both values proportionally to the new width and clamp scroll_position to stay in bounds.
