CobbleGacha Expanded Alpha 3.7.37

Server startup hotfix for 3.7.36:
- Fixes VerifyError in BannerTestRuntime.visibleBanners().
- The previous 3.7.35 runtime patch replaced conditional jumps with unconditional GOTOs, leaving boolean values on the JVM operand stack.
- 3.7.37 rebuilds BannerTestRuntime from the clean 3.7.34 class and applies the Standard Banner behavior safely.

Retained behavior:
- Standard can be deleted.
- Standard is no longer automatically reinserted when banner.order does not contain it.
- visibleBanners() no longer manufactures Standard when no banner is active.
- Strict custom-pool behavior from 3.7.35/3.7.36 remains unchanged.
- Editor deletion patches from 3.7.36 remain unchanged.

Verification:
- BannerTestRuntime passes ASM BasicVerifier analysis.
- StackMapTable frames are recomputed from scratch.
- No gameplay rates, pity, 50/50, IV or reward-probability changes.
