docs: write Full Example tutorial and fix stale references

- Replace the 'under construction' placeholder in get_started/full_example.md
  with the complete tutorial: selection screen, data read, result table,
  edit popup, and post - including the full class listing (verified with
  abaplint against the current framework source)
- Fix non-existent util method: trans_get_text -> text_get (logon_language.md)
- Update stale sample class references: DEMO_APP_135/137 -> DEMO_APP_S_01/S_02
  (statefulness.md), DEMO_APP_304 -> DEMO_APP_S_03 (audio.md, barcode_scanning.md)
- Normalize internal link style in ui5_versions.md

 ### Release-Specific
 Some controls and properties are only available on specific UI5 releases. The abap2UI5 framework and its samples support many UI5 versions, reducing compatibility issues. But when building your own apps, check compatibility with the UI5 version your system uses.
