Sublayers 7a-e need update to latest CR 7a-d

What used to be layers 7c and 7d have been merged - can't recall exactly when that changed:

https://github.com/magefree/mage/blob/bf2e90feaead6f96babc0538b37b34aa174fc1b0/Mage/src/main/java/mage/constants/SubLayer.java#L6-L15

https://yawgatog.com/resources/magic-rules/#R6134

We ought to refactor to align with the comprehensive rules

Start with Mage/src/main/java/mage/constants/SubLayer.java and compare its sublayer definitions with Comprehensive Rules section 613.4. Trace the usages of the affected 7a-e layers, then update the definitions and verify that the game's layer handling matches the current 7a-d structure.
