fix(blocks): reopen evaluated references in their authoring definition

Resolve BEDIT reference entry through the native dynamic-definition link instead of editing the anonymous geometry variant. Preserve static-block fallback and existing lock/xref checks.

Add synthetic regressions for evaluated-reference DWG reload and save/close/reedit, plus Rotation-only save/close/reopen followed by Flip placement. Validated with 334 block tests passing (6 existing opt-in tests ignored).
