Phase 2 TestUnlock handshake was synchronous (Thread.Sleep x 8 = 4 s) and
the continuation after Phase 1 marshalled back to the WPF dispatcher via
the captured SynchronizationContext, so the eight 500 ms sleeps froze the
UI right before unlock completed.
- UnlockService.RunTestUnlockSequence -> async RunTestUnlockSequenceAsync
with Task.Delay(500, ct) and ConfigureAwait(false)
- Add ConfigureAwait(false) on every internal await in UnlockService so
continuations no longer hop to the UI thread (Task.WhenAll, Task.Delay,
connectedTcs, TryFastUnlockAsync, fast-unlock settle delay)
- CancellationToken now propagates through Phase 2, so the snackbar Cancel
button can interrupt the handshake within 500 ms instead of waiting out
all eight Thread.Sleeps
Includes the companion observer in IUnlockService / UnlockService
(PumpUnlocked event, IsPumpUnlocked, StartObserver/StopObserver) that
the Phase 1 wait now races against — lets any source of unlock (fast
unlock, external manual, CAN flood finally working) short-circuit the
600 s timer as soon as the CAN TestUnlock parameter confirms it.

Unlock progress UI:
- UnlockProgressDialog with dark-themed progress ring, phase indicator, elapsed
time, and cancel/close buttons (non-modal, draggable borderless window)
- UnlockProgressViewModel with event-driven progress tracking via IUnlockService
- Triggers on pump selection (manual or K-Line auto-detect), not test start
UnlockService rewrite:
- Persistent CAN senders that outlive the unlock sequence (StopSenders on pump change)
- Concurrent K-Line fast unlock: awaits session Connected, sends RAM timer shortcut
({02 88 02 03 A8 01 00}), verifies via CAN TestUnlock before skipping wait
- Fix Type 1 verification (Value == 0 means unlocked, was inverted)
K-Line fast unlock support:
- IKwpService.TryFastUnlockAsync / KwpService implementation
Additional features:
- ILocalizationService with ES/EN resource dictionaries and runtime switching
- Safety dialogs: VoltageWarning, OilPumpConfirm, RpmSafetyWarning
- SettingsDialog for app configuration
- BenchService enhancements, ConfigurationService improvements, PDF report updates
- All UI strings localized via DynamicResource
