Pull request overview

This PR improves evmreader reliability through several interconnected changes: WebSocket subscription retry logic with liveness detection, idempotent input handling, input count validation against on-chain state, unified fetchInputs logic replacing duplicated code, and adapter caching with staleness detection.

Changes:

• Added WebSocket liveness timeout, retry counter reset logic, and Alive()/Ready() health checks backed by atomic.Bool
• Unified fetchInputsForEpoch and fetchApplicationInputs into a single fetchInputs method with bounds filtering, duplicate detection, and input count validation
• Introduced adapter caching per application address with config-change invalidation, replaced time.Sleep in tests with deterministic flushHeaders, and moved test infrastructure to dedicated files
