feat: add sidebar showOnHover support and drawers isOpen IPC (caelestia-dots#1505)

* feat: add sidebar showOnHover support and drawers isOpen IPC

- Add showOnHover property to SidebarConfig (defaults to false)
- Show sidebar on hover when cursor enters top-right corner
- Hide sidebar when cursor leaves sidebar area or exits screen
- Add sidebarShortcutActive flag to preserve shortcut-triggered state
- Add isOpen(drawer) to drawers IPC target for external state queries

Closes caelestia-dots#226

* docs: add sidebar showOnHover to config reference

* style: apply qmlformat to Shortcuts.qml

* fixes
