Refactor app services and stabilize refresh/UI flows

- Add refresh scheduler and network refresh service boundaries for typed
  refresh results, ordered RPC collectors, applicators, and price parsing.
- Add daemon lifecycle and wallet security workflow helpers while preserving
  App-owned command RPC, decrypt, cancellation, and UI handoff behavior.
- Split balance, console, mining, amount formatting, and async task logic into
  focused modules with expanded Phase 4 test coverage.
- Fix market price loading by triggering price refresh immediately, avoiding
  queue-pressure drops, tracking loading/error state, and adding translations.
- Polish send, explorer, peers, settings, theme/schema, and related tab UI.
- Replace checked-in generated language headers with build-generated resources.
- Document the cleanup audit, UI static-state guidance, and architecture updates.
