feat: upgrade crypto from bcrypto to noble

[acolytec3]

• Replaces the bcrypto dependency with a combination of @noble/hashes and @noble/secp256k1 (both are audited, modern, JS only ESM modules with no external dependencies)
• Removes bcrypto types
• Adds lint:fix script because eslint is your friend
• Selectively disabled eslint rules where necessary (mainly in tests where typescript would otherwise complain)
