fix(): Prevent RotationVolumeSplitProvider from intercepting unrelated boundaries

[benflexcompute]

RotationVolumeSplitProvider was aggressively intercepting any boundary containing __rotating_, causing false positives for user-defined boundaries or boundaries not generated by the current rotation configuration.
This PR implements a multi-layer defense:

1. Strict Name Checking: The provider now caches the exact full names it expects to generate and only intercepts those specific boundaries.
2. Active Volume Check: The provider is only added to the lookup table if there are active RotationVolume zones with enclosed entities.
3. Volume Mesh Bypass: The provider is skipped entirely when initializing from VolumeMeshEntityInfo, as split logic is unnecessary for pre-meshed volumes.
   Regression tests covering these scenarios have been added.
