Feature: #106828 - Add User TSconfig to define default Live Search action 

See forge#106828

Description 

A new User TSconfig options.liveSearch.actions has been introduced to allow an integrator to define default behaviors of a search result.

Available actions:

Action Description
edit This opens the editing form for the record (Default for all tables except pages)
layout This opens the page in the page module (Default for table pages)
list This opens the storage page of the record in the "Records" module
preview This opens the record in the frontend

Examples 

Set default for all tables

options.liveSearch.actions.default = edit

Set default for table tt_content

options.liveSearch.actions.tt_content.default = layout

Set default for custom table

options.liveSearch.actions.my_table.default = preview

Impact 

Live Search default actions can now be configured via User TSconfig. Integrators can define global or per-table behavior for search results, improving backend workflows.

The default behavior for pages has been changed to layout to improve the user workflow.
