Remove dead code: ~21,100 lines of unused P2P, legacy challenge, and jobs code

Major removals:
- crates/challenge-runtime/ (entire crate - unused epoch sync)
- crates/network/ (entire P2P networking crate - previously removed)
- platform-server: rule_engine.rs, challenge_proxy.rs, api/jobs.rs, api/llm.rs
- platform-server: 20+ unused db query functions, AuditLogger system
- challenge-sdk: P2P modules (p2p.rs, distributed_storage.rs, etc.)
- distributed-db: p2p_sync.rs

Cleaned:
- Unused struct fields in csudo, data_api, websocket
- Dead auth functions (require_auth, require_validator, require_owner)
- Unused Cargo.toml dependencies in platform-server

All code compiles cleanly with cargo check.
