Expose the taproot script TLV codec so wallet-side import routing can
persist encrypted script material through the store seam.

Expose whether a managed public-key address carries encrypted
private-key material. The kvdb adapter's address lookup uses this
in the watch-only address-info computation: an imported address
under a spendable wallet is watch-only at the address row when
its underlying `managedAddress` has no encrypted private key.

Extracted from the original `kvdb+waddrmgr: add address lookup`
commit so the waddrmgr export sits on prep-address-manager-store
and the kvdb consumer stays on impl-address-manager-store.

Disambiguates P2TR key-path vs script-path imports — output type
alone is ambiguous.

PubKey return on derivedAddressInput + DerivedAddressData. addrSchema
parameter so derivedAddressInput honors per-account overrides instead of
re-reading scope default. Adds GetAccountAddrSchema adapter field with
pg/sqlite scope-default implementations.

Adds AccountNumber, AccountName, KeyScope, MasterKeyFingerprint to
AddressInfo and AddressInfoRow. Introduces convertAccountMetadata +
convertAddressAccountMetadata + ApplyAddressAccountMetadata so SQL
adapters can populate these fields on create + read paths.

SELECT account_master_fingerprint + wallet_master_hd_pub_key from
the wallets/accounts JOIN already present in GetAddressByScriptPubKey
and ListAddressesByAccount. Regenerates sqlc.

Create + read paths now route through the new helper so AddressInfo
returns AccountNumber + AccountName + KeyScope + MasterKeyFingerprint
on both backends.

Move the shared SQL derived-address adapter helpers out of the mirrored pg/sqlite closures before wiring IsUsed query projections.

The account-schema helper uses the persisted key-scope address type IDs so SQL derived address creation honors stored scope schema overrides.

See ADR 0011 for SQL/kvdb derivation asymmetry.

Wires GetAddressByScriptPubKey + ListAddressesByAccount through EXISTS(SELECT 1 FROM utxos WHERE address_id = ?). The Store interface has no SQL MarkAddressUsed method: the tx-record path already writes the utxos row that the EXISTS derivation reads.

Annotates 000006_addresses.up.sql so a future contributor reaching for the column finds ADR 0011.
