feat(library): tags + tag filtering, monochrome icons; fix live tag updates

- library: expose page tags (batch), render tag chips per row and add a tag
  filter bar; register tag create/associate/remove in the shared context menu
  exactly like local-workspace
- library: restore monochrome SVG icons (folder/edit/image/file) matching
  local-workspace, with optional custom page_icon
- workspace: refresh tag chips/filter live on tag add/remove (reassign arrays
  + tagsVersion) instead of requiring a page reload
- ctxmenu: measure the rendered menu and clamp it to the viewport on open
