Refactor tests to BTT

[maxnorm]

Summary

Refactor tests suite based on the new facet structure and the BTT approach

Changes Made

• Refactored test suite to BTT structure: Reworked tests to follow the new facet-based layout and BTT (behavioral test tree) approach.
• Removed legacy monolithic tests: Deleted old AccessControl and Owner test files and their associated harnesses.
• Added BTT tree specs: Introduced AccessControl.tree and Owner.tree specifications to describe test behavior trees.
• Added new access test harnesses: Implemented AccessControlCoreMod, AccessControlPausableMod, AccessControlTemporalMod, OwnerCoreMod, and OwnerTwoStepMod harness modules.
• Expanded AccessControl unit tests: Added tests for admin, batch grant/revoke, data, grant, pausable, renounce, revoke, and temporal data/grant/revoke behaviors with base + facet/mod fuzzing.
• Expanded Owner and OwnerTwoSteps unit tests: Added data, renounce, and transfer tests for both Owner and OwnerTwoSteps, again with base + facet/mod fuzzing.
• Introduced storage utilities: Added AccessControlStorageUtils.sol and OwnerStorageUtils.sol to standardize test storage setup.
• Adjusted ERC165 storage slot: Updated ERC165 tests and harnesses to use keccak256("erc165") as the storage slot instead of keccak256("compose.erc165").
• Added ERC1155 BTT tests: Introduced behavior-tree-style tests for the ERC1155 implementation.
• Completed ERC20 BTT tests: Finished converting/adding ERC20 tests to the new BTT pattern.
• Split exportSelectors test: Moved export selector tests into a dedicated exportSelectors test file.
