Expand scan to Pictures/ subdirs, add app folder exclusions

AndroidConnector: scan both /storage/emulated/0/DCIM and
/storage/emulated/0/Pictures — all subdirs of each.

ExifFilter: add Slack, Teams, Zoom, Discord, sticker, gif, avatar,
profile, thumbnail, cache to excluded path fragments. These land in
the Other section of the folder panel.
