Subject: [PATCH] fuzz: remove splicing blocks in chanmon_consistency_target

Removed !cfg!(splicing) blocks to enable full coverage of splicing
logic during fuzzing. Verified by running the fuzzer for 15 minutes
before and after the changes.

Fuzzing Validation (chanmon_consistency_target):
Metric        Before      After       Change
cov           37824       38686       +862
ft            155421      168662      +13241
corp          1545        1851        +306

The increase in coverage confirms that the splicing logic is now
reachable and being actively fuzzed.
