Add a fuzzy mode to the explorer search: a non-numeric, non-full-hash query now
filters the list to cached blocks whose hash (or height text) contains the query
substring, live as you type. Backed by a new ExplorerBlockCache::searchBlocks()
(SQLite LIKE with escaped wildcards), memoized per query so it doesn't hit the DB
every frame. Exact queries still navigate precisely: a block height re-anchors
the list, and a full 64-char hash is resolved via RPC. Row clicks still open the
detail modal. Empty results show "No matching cached blocks".
Note: fuzzy matching covers cached (browsed/prefetched) blocks only — the daemon
has no partial-hash index — while exact height/hash lookups reach any block.

Add an encrypted SQLite transaction history cache with cached tip metadata and
per-address shielded scan progress so startup and full refreshes avoid
re-scanning every z-address while still invalidating on wallet/address/rescan
changes.
Improve wallet history loading by paging transparent transactions, preserving
cached shielded and sent rows, keeping recent/unconfirmed activity visible, and
classifying mining-address receives. Show z_sendmany opid sends immediately in
History and Overview, pin pending rows through refreshes, and apply optimistic
address/balance debits until opids resolve.
Add timestamped RPC console tracing by source/method without logging params or
results, reduce redundant refresh/RPC calls, and cache Explorer recent block
summaries in SQLite.
Expand focused tests for transaction cache encryption, scan-progress
persistence/invalidation, history preservation, operation-status parsing,
pending send visibility, and Explorer/RPC refresh behavior.
