- useFocusEffect re-reads auto_import_path from DB every time the Import
tab is focused, so the scan button appears immediately after saving in
Settings (was broken by conditional hook call which violated Rules of
Hooks and never re-fired on setting changes)
- Nested inner try/catch isolates DocumentPicker.getDocumentAsync so
ActivityNotFoundException (Karoo has no DocumentsUI) shows a friendly
message instead of crashing the tab
- Settings watch-directory placeholder updated to /sdcard/FitFiles
