refactor: update nostr-tools imports for better tree shaking

Changes:
- Import specific functions from nostr-tools instead of full module
- Replace nip06.accountFromExtendedKey with direct import
- Update related function calls to use imported version

This change reduces bundle size by enabling better tree shaking
of unused nostr-tools functionality.
