root 3fb832e578 PPTX connectors: emit native bentConnector2/3/5 instead of disjoint lines ...

Spec authors hand the renderer a polyline like
``points: [[210,280],[400,280],[700,130]]``. The previous code emitted
one ``prst="line"`` shape per segment, so the elbow was two separate
straight lines that PowerPoint cannot recognise as a connected path.

The OCI template (kb/diagram/assets/OCI_Icons.pptx) uses native
PowerPoint bent connectors instead — 98 ``straightConnector1`` plus
22 ``bentConnector2/3/5`` plus 15 ``line`` across 48 slides. Match
that convention:

  • 2 points  → straightConnector1 (one segment, unchanged)
  • 3 points  → bentConnector2     (one elbow)
  • 4 points  → bentConnector3     (S-shape, two elbows)
  • 5+ points → bentConnector5     (four elbows)

The rasterizer (oci_pptx_render.py) now also understands bentConnectorN
so the local PNG preview matches what real PowerPoint draws — without
this it rendered every connector as one straight diagonal regardless of
the prst.

Persistent: applies to every absolute_layout connector for every spec,
not a per-case patch.
