fix(ctxmenu): repair library rendering and complete unified row menu

- library.html: remove leftover syntax error + orphan </template></div> that
  broke libraryPage() (page showed 'undefined' and no files), call the correct
  fdCtx.openMenu and use self instead of a throwaway libraryPage() instance
- _ctx_menu.html: full conventional menu with shortcuts, tags + colour picker,
  edit-icon picker; closes on outside click and Escape
- local_workspace.html: migrate onContextMenu to the shared fdCtx store with
  complete handlers; drop legacy window._ctxMenuData DOM hacks
- dashboard.py: expose page_icon + favorited in the workspace tree
