Simplify device info access and reorganize documentation

[oblomov-dev]

Summary

This PR simplifies how developers access device information in abap2UI5 by removing the need for a custom control and complex event binding. Device data is now directly available via client->get( )-s_device on every roundtrip. Documentation has been reorganized to reflect this simpler approach and to better distribute content across related topics.

Key Changes

• Simplified Backend Device Access: Replaced the info_frontend custom control pattern with direct access to client->get( )-s_device. Developers no longer need to:

  • Define multiple ABAP attributes for device properties
  • Use two-way binding (_bind_edit) to collect values
  • Wait for a finished event before accessing device data

• Updated Device Model Documentation:

  • Clarified that backend access now uses client->get( )-s_device instead of custom controls
  • Replaced the lengthy example class with a concise code snippet showing direct property access
  • Removed reference to the Z2UI5_CL_DEMO_APP_122 example

• Reorganized Info Documentation:

  • Moved detailed device property examples from info.md to device_model.md to consolidate device-related content
  • Converted info.md into a navigation hub with brief descriptions and links to detailed documentation
  • Reduced redundancy by pointing readers to the appropriate detailed pages

• Enhanced Focus and Scrolling Documentation:

  • Added "Read the Current Focus" section to focus.md with code examples for accessing client->get( )-s_focus
  • Added "Read the Scroll Position" section to scrolling.md with code examples for accessing client->get( )-s_scroll
  • These sections were previously only in info.md and are now in their respective feature pages

Implementation Details

The changes maintain backward compatibility in terms of API (the client->get( )-s_device structure remains the same), but simplify the developer experience by eliminating the custom control boilerplate. Documentation now follows a clearer pattern where each feature page contains both reading and writing operations for that feature.
