v1.0.27: knot-inspired icon, fix media-not-found on photo open

Icon: two thick tube-style arcs with 3D glossy highlights.
  Arc 1 (left side): coral #E8665A to orange #E8A040
  Arc 2 (right side): steel blue #4A7FD4 to deep purple #7B5EA7
  Arrowheads: orange and purple. Background: dark purple-black.
  Inspired by the braided knot color palette.

Fix "media not found" when opening photos:
  - Intent now sets ClipData alongside FLAG_GRANT_READ_URI_PERMISSION
    so the permission correctly propagates through the system chooser
    to whichever app the user picks.
  - openFile() and downloadToCache() both call MediaScannerConnection
    so newly synced/downloaded files appear in gallery MediaStore index
    before the viewer launches.
