gaiad: v27.4.0 + statesync-skip-if-data + wasm-snapshot seed (port cursor host fix)

Browse Source 
Live chain is v27.4.0 (abci_info); v25.3.2 halts at the v26/v27 upgrade heights (ghcr
lags but v27.4.0 IS pullable). Statesync omits CosmWasm + IBC 08-wasm files -> gaia panics
'wasmlckeeper failed initialize pinned codes / Error opening Wasm file'. init.sh now: skip
statesync if data/application.db exists (idempotent restart, preserves a restored snapshot);
on fresh statesync, seed wasm from polkachu cosmos_wasmonly.tar.lz4. Porting cursor's host
fix into the repo (host /root/rpc edits get reverted by run-rpc-update re-clone).
