fix: decode legacy prefixless cashaddr and support testnet extended keys - #4
Conversation
Production dry-run findings: legacy AbcPay stored prefixless cashaddr with empty-prefix checksums, which decodeAddress/validateAddress rejected because they force the ecash: prefix, and testnet DOGE wallets failed derivation because @scure/bip32 defaults to mainnet version bytes. wallet-core now tries prefixed and prefixless forms when decoding XEC addresses and falls back to testnet xpub/tpub versions. The import audit compares decoded scripts (type + hash160) instead of raw address strings, and non-livenet wallets are skipped until v2 has testnet Chronik endpoints. Dry run on the production bws snapshot: 5,157 wallets seen, 5,142 in scope (XEC 899: 1,892 / XEC 1899: 2,984 / DOGE: 266), 41 skipped (15 Raipay + 26 testnet), 0 failed, 5,576 addresses audited, 0 mismatches.

…ames RaiPay XEC wallets use the 145 account path; they are now mapped during import and included in the restore probe candidates (default, alternative, 145). Legacy wallet and copayer names are sjcl-encrypted JSON and exceed the 100-char columns; imports now use fallback display names (Wallet <id8>, Copayer <id6>) and each wallet is inserted in a transaction so a failure cannot leave a wallet without its copayers. Applied to the production bws snapshot: 5,131 wallets imported (XEC 899: 1,892 / XEC 1899: 2,984 / XEC 145: 15 / DOGE: 240), 26 testnet skipped, 0 failures, 5,434 addresses audited with 0 mismatches.

Fail the transaction when a child conflict prevents a complete import.
The wallet pre-check does not validate existing copayers or copayer_lookup rows. Both tables have unique copayer_id columns, but no foreign keys enforce the matching wallet_id. A conflicting child row can therefore be ignored by ON CONFLICT DO NOTHING. The transaction commits, and line 200 counts the incomplete wallet as imported.
All three inserts use ON CONFLICT DO NOTHING. Validate conflicting rows and throw when their wallet_id or values differ. Also verify that the wallet insert succeeded before inserting child rows.

Do not swallow probe errors. wallet.service.ts returns copayerExists: false for an ordinary credential mismatch, but it throws for operational failures. This catch treats both cases as mismatches. The later api.joinWallet call can then insert the unverified credentials as a copayer. Let probe errors propagate; only continue to the next candidate when the probe returns copayerExists: false.
