Connecting via the device flow saved the token to prefs but had no effect:
the capture screen cached its settings from launch and only re-adopted them
when Settings was popped *with a result*, which the connect flow never did.
So auto-sync kept using stale (token-less) settings (notes never downloaded)
and reopening Settings re-seeded the fields from the stale settings (empty
token → Test connection failed, Connect restarted every time).
- settings: on a successful connect, save then run a sync right away and
report the result ("Connected and synced …") so notes download and the
user gets real confirmation, instead of the inert "Token saved on Save".
- capture: always reload settings from storage after returning from Settings,
so a device-flow connect (which saves without popping a result) is picked up.
- tool/device_flow_check.dart: standalone end-to-end device-flow probe used to
confirm the OAuth App + token + repo-access chain is healthy (it is); the bug
was purely app-side token application.
