feat(explorer): live (debounced) search as the user types

Browse Source 
The explorer search only ran on Enter or the Search button. Now it also fires
automatically ~350ms after the user stops typing, once the query is resolvable
— a block height (all digits) or a complete 64-char hash/txid. Partial hex is
ignored so it won't flash "invalid query" mid-type, per-keystroke RPC spam is
avoided via the debounce, and the same query isn't re-run. Enter/button still
work for an immediate search.
