Fix share copy-link, destination-picker filters, and type-filter UX

- SharesController's fetchShares() built NextcloudShare objects through
  its own thin inline parser instead of _shareFromJson, so url/token/
  permissions/expireDate were always null - a public link share could
  never show "Copy link" in the Shares tab. Reuses _shareFromJson.
- Upload/Move/Copy's destination picker hid External storage in its
  filter sheet (showStorageScope: false) unlike Files' own controls
  row, despite the design doc already calling for full parity.
- Files' and Photos' type filter (All/Files/Folders, All/Photos/Videos)
  now render as one consistent style in both filter sheets: every icon
  always shown, label only on the selected segment
  (NooSegmentedControl's new labelOnlySelected), replacing Files' old
  checkmark list and Photos' own always-labelled track.
- Fixes Photos' type filter only visually updating after closing and
  reopening the filter sheet - it lived on PhotosView's own State, so
  Listenable.merge([photos, files]) never rebuilt the sheet when it
  changed; a StatefulBuilder now gives it that trigger.
- Replaces Settings' trailing section jump rail with per-section
  collapsible cards (NooGroupedList's new collapsible param, expanded
  by default) - one less parallel way to navigate a long screen.
