Add quickCrypto patch for nested @scure/bip32 in cashu-ts

Browse Source 
Patch cashu-ts's nested @scure/bip32@2.0.1 dependency to use
react-native-quick-crypto for HMAC-SHA512 operations in BIP32
key derivation. This improves wallet recovery performance.

- Add patches/@cashu+cashu-ts++@scure+bip32+2.0.1.patch
- Enable scripts in .yarnrc.yml for patch-package
