fix: direct sidebar refresh via window.appState instead of events

Replaced the fragile event-based sidebar refresh with direct function calls:
- appState.init() now sets window.appState = this
- _reloadAfterAction(), doCreate(), deleteWithUndo() call
  window.appState.refreshSidebarTree() directly (no DOM event)
- Sidebar handlers (drop, deleteWorkspacePage, wsCtxAction, newFolder)
  call window._wsData._reloadAfterAction() directly (no DOM event)
- Removed event listeners for flowdeck:workspace-changed and
  flowdeck:sidebar-refresh from local_workspace.html

This is more reliable than CustomEvent which had timing/scope issues.
