Sync current sources: clean RAP handover names, app rebind, tooling

Working-tree state as of 2026-09-29, uncommitted since the initial
"upload current sources" commit:

- docs/handover/rap/: renamed the 11 generator-suffixed sources
  (zz*000) to the clean object names built on the tenant, plus the
  A2X leg and parameter-entity edits.
- app/: manifest, annotations, i18n, mock data and local/mock ui5
  configs updated to the live service shape.
- PRD.md, CHANGELOG.md, KNOWLEDGE.md: build record through
  2026-09-19, including the rejected reentrance-ticket path.
- tools/adt-reentrance-login/: retained login helper (new).
- docs/v2/zui_arena_change_appr_o4.metadata.xml: captured live
  $metadata (new).
- Dropped a stray 0.3GB-class Eclipse installer that the initial
  commit had tracked under a URL-mangled filename, and the
  machine-specific 0M7DEJI.code-workspace.
