Route the flatStateCodec from Database through every flat-state call
site so that the trie-specific aspects of persistence and key derivation
live behind a single abstraction. Pure refactor: merkle behavior and
on-disk layout are unchanged because the only codec wired up is
merkleFlatCodec, whose methods are thin wrappers over the existing
rawdb accessors.
Threaded sites:
disklayer.account/storage use codec.{Read,AccountCacheKey,
StorageCacheKey} instead of direct
rawdb calls and bare hash slicing.
flush.writeStates takes a codec parameter; persistence
goes through codec.{Write,Delete}
{Account,Storage}.
buffer.flush carries the codec down into writeStates.
states.write/dbsize takes the codec for prefix-size
accounting.
generate.go (g.codec) the generator owns a codec, used by
generateAccounts/generateStorages
callbacks; the unused top-level
splitMarker helper is removed in favor
of codec.SplitMarker.
context.go the generator context owns the codec
and uses codec.{AccountPrefix,
StoragePrefix,Account/StorageKeyLength}
to construct iterators.
reader.go (HistoricalState) uses codec.{Account,Storage}Key for
caller-side key derivation.
The marker comparisons in writeStates remain merkle-shaped (two-tier
account+storage marker) because the bintrie path will use a separate
writer over single-tier stem markers in a later commit.
All existing pathdb tests pass.
