refactor: zombienet-sdk rebrand and subxt compatibility fixes

Zombienet-SDK changes:
- orchestrator: sc-chain-spec → pezsc-chain-spec
- orchestrator: sp-core → pezsp-core imports
- orchestrator: k8s-openapi v1_27 → v1_28
- provider: k8s-openapi v1_27 → v1_28
- sdk: k8s-openapi v1_27 → v1_28

Subxt vendor fixes:
- Enable std features (remove default-features = false)
- Fix lifetime annotations for Rust 2024 compatibility
- Fix ecdsa/sr25519 password type conversions
- Fix RecoveryId API change (i32::from → to_i32)

Dependencies:
- wasmtime: 35.0.0 → 37.0.0 (security fix)
- tracing-subscriber: 0.3.18 → 0.3.20 (security fix)
- thiserror: 1.0.64 → 2.0.17

Note: ring 0.16.20 vulnerability remains - requires libp2p 0.56
upgrade which needs extensive pezsc-network API changes.
