feat: add T4 menu dumping and loading (#986)

* feat: add T4 menu dumping

* chore: align with latest changes

* feat: add T4 menu loading

Load T4 menulists and menu files through the shared menu parser.

Preserve T4-specific menu and listbox fields and cover loading, dumping, linking, and round-trip behaviour.

* chore: make flag fields unsigned

* chore: rename `expOperationEnum` -> `operationEnum`

* chore: use default enum numeration for T4 operationEnum

* chore: remove unused members of operationEnum

* chore: remove redundant op from operationEnum

* refactor: align T4 expression operand names with IW3

* chore: small adjustment to iw3,t4 types
