feat(auths-sdk,auths-core,auths-cli): stabilize core architecture & error boundaries

[bordumb]

Summary

• fn-33.1: Replace SdkStorageError::OperationFailed(String) with 5 typed #[from] variants (Identity, Init, AgentProvisioning, Driver, Attestation) — eliminates stringly-typed error wrapping in setup.rs and device.rs
• fn-33.2: Implement AuthsErrorInfo for TrustError, SetupError, DeviceError; register SDK errors in CLI renderer downcast chain for structured JSON/text error output
• fn-33.3: Audit all core/SDK crates for unwrap() in production code — none found; promote unwrap_used and expect_used workspace lints from warn to deny; add #![allow(...)] to auths-test-utils
• fn-33.4: Add --json output to auths device list via DeviceEntry struct and JsonResponse<T> pattern

Test plan

• cargo nextest run --workspace — 1567/1567 passed
• cargo test --all --doc — 3 passed, 0 failed
• All pre-push hooks passed (fmt, clippy, deny, wasm, cross-check)
