wip(hook): retained client-hook WIP \u2014 resolver_hook, store_hook, openfut-common crate

RETAINED PRE-EXISTING client-hook WIP (brought forward after verification).
Adds resolver_hook.rs + store_hook.rs and a new openfut-common crate, plus
config/connect/fifa17/hooks/lib refinements. No secrets/staging addresses.
Preserved on feat/sbc-hook-tracing so it is recoverable and pushed.
