+Feat(webapp): animated resizable panel
+
+Adds animated open/close transitions to Resizable panels using react-window-splitter built-in animation hooks. Includes new exports: RESIZABLE_PANEL_ANIMATION, collapsibleHandleClassName(), and useFrozenValue(). Converts inspector/detail side panels from conditionally-mounted to always-mounted collapsible panels across multiple routes (batches, runs, schedules, deployments, logs, waitpoints, bulk-actions).
