hygiene: Phase 3 follow-up — sweep commented-out debug cruft

Remove ~116 commented-out debug/dead-code lines the audit flagged as noise
(findings F6/F7/F15/F22): the Komodo "%s tikN" step-tracer comments and other
commented-out fprintf/printf/LogPrintf/std::cerr calls threaded through
AppInit2 (init.cpp), CreateNewBlock and the miner loops (miner.cpp), plus a
few commented-out dead-code fragments (sendmany SetLockTime/nLockTime, the
CCtx CC_vinselect random-pick block and AddNormalinputsLocal remote-mypk
redirect, miner adaptive-PoW assignments).

Comments only — no compiled behavior changes; the tree builds clean.
