feat(quick-sync): TCT frontier support (#2303)

## Description of Changes

quick sync using the state commitment tree snapshots to initialize the
view server for freshly generated wallets.

currently failing on mainnet with `ConnectError: [unimplemented]` when
attempting to call the SCT frontier service, but works with testnet rpc.
