feat(esplora)!: remove EsploraExt::update_local_chain

Browse Source 
Previously, we would update the `TxGraph` and `KeychainTxOutIndex`
first, then create a second update for `LocalChain`. This required
locking the receiving structures 3 times (instead of twice, which
is optimal).

This PR eliminates this requirement by making use of the new `query`
method of `CheckPoint`.

Examples are also updated to use the new API.
