fix: clippy warnings and add mandatory CI hooks

CI/CD:
- Pre-push hook runs: format check, cargo check, clippy, tests
- Clippy allows patterns intentional in codebase
- Hook script in .githooks/pre-push with install.sh

Fixes:
- sr25519 migration for data_gossip.rs and auth.rs
- Dead code annotations for unused fields
- Consistent digit grouping in numbers
- Redundant field names removed
- Module naming conflict fixed
- Simplified JSON-RPC status code
- Updated Docker image whitelist
