feat: add permissions to NIP-46 connection URI for Amber compatibility

- Include explicit permission list in nostrconnect:// URI
- Request signing permissions for common event kinds (notes, reactions, zaps, etc.)
- Request NIP-04 and NIP-44 encryption/decryption permissions
- Improves compatibility with Amber and other NIP-46 signers
- Follows NIP-46 specification for permission grants
