Odoo Studio now lets users add line-item lists to custom apps directly from the model configurator or by dragging a new Lines field into a view. This removes several manual setup steps, making custom business workflows with related detail lines faster and easier to build.

Odoo Studio now lets users add line-item lists to custom models directly from the model configuration or by dragging a Lines field into a form. This removes several manual setup steps, making it faster and simpler to build parent records with related line details.

Currently, in order to have a 'lines' listview on a custom model, the user has to:
1. create a secondary 'lines' model
2. link this model to the 'parent' model with a many2one
3. create the counterpart one2many field on the 'parent' model

in this commit,
1. can add line by select lines option from model configuration.
2. can add line by drag and drop lines field from side panel.
