Historical Session Replay v15.10.214 — presentation-only Stats Corner tidy

Scope:
- Ultimate AI graph labels remain vertical on/above their bars, preserving the accepted original presentation.
- AI Hxx £xx.xx labels enlarged from 8pt to 10pt for clarity.
- Rotated label placement now reserves the complete rendered text width above each bar, preventing top-edge cropping.
- Session 13 reconstruction/comparison fixes from v15.10.213 are retained unchanged.
- No evidence values, calculations, controller logic, comparison logic, or Live GUI behaviour changed.
- CLI remains V9.2.53. Live GUI remains v15.10.140.

Build verification:
- BlackjackSessionReplay.java compiled successfully.
- Runnable BlackjackSessionReplay.jar rebuilt from this source.
- No loose .class files included in GUI distribution.
