[refactor](trx-rs): resolve all P1/P2 improvement areas
P1 (High Priority):
- Fix LIFO command batching in rig_task.rs (batch.pop→batch.remove(0))
- Add ±25% jitter to ExponentialBackoff to prevent thundering herd
- Add 10,000-entry capacity bounds to decoder history queues
- Add rig task crash detection with Error state broadcast
- Decompose FrontendRuntimeContext 50-field god-struct into 9 sub-structs
(AudioContext, DecodeHistoryContext, HttpAuthConfig, HttpUiConfig,
RigRoutingContext, OwnerInfo, VChanContext, SpectrumContext, PerRigAudioContext)
- Migrate std::sync::RwLock to tokio::sync::RwLock in background_decode.rs
- Extract find_input_device/find_output_device helpers from audio pipeline
P2 (Medium Priority):
- Introduce SoapySdrConfig builder struct (replaces 20+ positional params)
- Add define_command_mappings! macro for ClientCommand↔RigCommand mapping
- Replace silent lock poison recovery with lock_or_recover() warning logger
- Make timeouts configurable via RigTaskConfig/ListenerConfig and TOML
- Extract shared config types to trx-app/src/shared_config.rs
