Replaced SQLAlchemy ORM with direct sqlite3 queries in unified_genesis.py initialize_genesis_database function to simplify database operations and remove dependency on SQLModel Session.
Added genesis command group to CLI with init, verify, and info subcommands for genesis block and wallet management. Implemented handlers for genesis operations including initialization, verification, and information display
Pydantic v2 requires all class attributes to be annotated. genesis_candidates
is a class-level constant, not a field, so it should be annotated as ClassVar.

Ran poetry lock to update lock files with new dependency versions:
- pytest: 8.2.0 → 8.3.0 (fixes tmpdir handling vulnerability)
- python-multipart: updated to latest version (fixes DoS vulnerability)
