feat(new-app): add --frontend, --route and align option names with frappe

[netchampfaris]

bench new-app can now be run fully non-interactively, making it easier to use in agents and CI pipelines.

Usage

bench new-app my_app \
  --title "My App" \
  --description "My app description" \
  --publisher "ACME Corp" \
  --email "dev@example.com" \
  --license mit \
  --frontend --route m \
  --github-workflow \
  --branch main
