perf(css): add CSS containment to floating windows

Added `contain: layout paint` to modal, subagent-window, log-viewer-window,
image-popup-window, plan-file-window, and plan-file-manager. This tells
the browser that these elements' layout and paint are independent from
the rest of the page, enabling rendering optimizations.
