The license labels for the Point of Sale preparation display modules have been corrected from LGPL-3 to OEEL-1. This ensures the modules are classified under the appropriate enterprise license, helping maintain accurate compliance and product packaging information.

before this commit, for the pos_preparation_display and pos_restaurant_preparation_display modules, the license is added as LGPL-3

after this commit, license of both the modules will be updated to OEEL-1.
