Refactor demo apps: standardize naming and improve code organization

[oblomov-dev]

Summary

Refactored multiple demo application classes to improve code consistency, naming conventions, and overall structure. The changes focus on standardizing type naming, reorganizing method visibility, and improving code readability.

Key Changes

Type Naming Standardization

• Renamed all custom types to follow ty_s_* (struct) and ty_t_* (table) naming convention
  • s_suggestion_items → ty_s_suggestion
  • s_suggestion_items_city → ty_s_city
  • s_employee → ty_s_employee
  • suggestion_item → ty_s_suggestion_item
  • combobox_item → ty_s_combobox_item

Data Member Reorganization

• Moved client reference to PROTECTED section for consistent access across methods
• Renamed screen structure from screen to s_screen for clarity
• Renamed table variables to use t_* prefix (e.g., mt_suggestion → t_suggestion)
• Removed redundant _sel table variants where possible

Method Refactoring

• Renamed interface methods to remove z2ui5_ prefix for cleaner code:
  • z2ui5_on_init → on_init
  • z2ui5_on_event → on_event
  • z2ui5_on_rendering → view_display
• Moved methods to PROTECTED section for better encapsulation
• Consolidated popup methods into single responsibility methods (popup_value_suggestion, popup_value_employee)

Code Quality Improvements

• Replaced single-quoted strings with backtick notation for consistency
• Improved method organization by moving initialization logic into on_init
• Simplified event handling flow in on_event
• Removed unused variables and redundant code
• Enhanced code formatting and indentation consistency

Affected Classes

• z2ui5_cl_demo_app_009 (major refactoring)
• z2ui5_cl_demo_app_008 (method reorganization)
• z2ui5_cl_demo_app_010 (structure improvements)
• z2ui5_cl_demo_app_002 (type naming)
• z2ui5_cl_demo_app_004 (data organization)
• z2ui5_cl_demo_app_006 (data organization)

Implementation Details

• All functional behavior remains unchanged; this is purely a refactoring
• Type definitions now consistently use the ty_ prefix pattern
• Client reference is stored once in main and reused across methods
• String literals standardized to backtick notation for ABAP 7.4+ compatibility
