Rename config directory to avoid collisions

The application was failing to build due to the presence of the
"config" directory, which seems to conflict with the generation
of files with "flutter config" during builds with meta-flutter's
flutter-app bbclass.  Rename the directory and update references
to it to allow building.

Initial cleanup push.

Based on agldemo2024 on commit 2a5dc04d801134338150c3f6afc67eaa65599763

Disable device preview.

Disable Lottie animation.

The original commit was b3c493c340fcb4bb0a937692838fc830bec3e9ea
but I am just keeping this change, because the json did not really
needed to change. I think.
