cometbft: WS Upgrade matcher case-insensitive + ct_ensure_wasm + statesync-skip-if-data

Browse Source 
Per cursor cosmos handoff. (1) Traefik WS router rule Headers(Upgrade,websocket) is
case-SENSITIVE -> clients sending 'Upgrade: WebSocket' (python websocket-client) fall
through to the RPC router (200/400 not 101). rpc-client.yml now emits
HeadersRegexp(Upgrade,(?i)websocket) for all split-WS chains; regenerated cosmos+avalanche.
(2) Refactor into cometbft-common.sh: ct_configure_statesync skips if data/application.db
exists; new ct_ensure_wasm seeds CosmWasm/IBC-08 wasm (statesync omits them). init.sh calls
both. README documents wasm/version/WS gotchas. 45 other split-WS composes get HeadersRegexp
on their next regen.
