docs: warn about data loss on uninstall when DataPath is default

Add a warning under the AppData path in system configuration,
shown only when dataPathSource is Default — these users would
otherwise lose their DB, covers, configs and backups silently
when uninstalling, since the Velopack install root and the
anchor coincide. Users who have already moved DataPath outside
the install tree don't see the notice (their data is safe).

resolves #1072
