Update package dependencies and refactor types in Nostr-related components

- Upgrade @types/node to version 22.18.1 and add @types/qrcode version 1.5.5 in package.json and package-lock.json.
- Refactor cleanupInterval and reconnectInterval types from NodeJS.Timeout to number in various Nostr-related files for better type compatibility.
- Enhance error handling in useNostrclientHub and useNostrChat components by specifying error parameter types.
