fix: use Ctrl+Shift modifier for sidebar toggle shortcuts

Sidebar toggle shortcuts (w, n, m, a) had no modifier keys, making them
isReservedByTextInput=true. When a sidebar opened and its search box
gained focus, the keybind handler skipped the shortcut, preventing
toggle-off. Adding Ctrl+Shift modifiers (VS Code style) ensures
isReservedByTextInput=false so shortcuts fire even with input focused.

Relocate Comfy.ToggleLinear from Ctrl+Shift+A to Ctrl+Shift+D to avoid
conflict with the new Workspace.ToggleSidebarTab.assets binding.
