The TSS native bridge returns signatures in Base64 format, but the
broadcast function expected hex format. Added Base64 decoding in
broadcastTransaction() to properly parse r, s, v components.

Extract current round number from tss-lib message type string using
regex pattern `Round(\d+)`. This enables real-time progress updates
(1/4, 2/4... for keygen, 1/9, 2/9... for signing) instead of only
showing completion status.
Changes across all three platforms:
- tss-wasm/main.go: Add extractRoundFromMessageType() and call
OnProgress with parsed round on each outgoing message
- service-party-android/tsslib/tsslib.go: Same implementation for
Android gomobile binding
- service-party-app/tss-party/main.go: Same implementation for
Electron subprocess, with isKeygen parameter to distinguish
keygen (4 rounds) vs signing (9 rounds)
Safe fallback: Returns 0 if parsing fails, which doesn't affect
protocol execution - only UI display.

The session event gRPC stream may silently disconnect without triggering
onError or onCompleted callbacks. This causes session_started events to
be lost, preventing the sign process from starting.
Changes:
- Add ensureSessionEventSubscriptionActive() to refresh event subscription
- Call it in joinSignSessionViaGrpc for sign joiner
- Call it in createSignSession for sign initiator after auto-join
This ensures a fresh event stream connection before waiting for events.

Critical fixes to prevent app crashes when screens are kept open for extended periods:
- Add repositoryScope with SupervisorJob for structured concurrency in TssRepository
- Replace detached CoroutineScope(Dispatchers.IO).launch with repositoryScope.launch:
- Session event subscription (line 206)
- Session status polling (line 291)
- Message routing (line 1508)
- Add cleanup() method to properly cancel all jobs and repositoryScope
- Update disconnect() to also cancel sessionStatusPollingJob
- Update MainViewModel.onCleared() to call repository.cleanup()
This ensures all background coroutines are properly cancelled when the ViewModel
is cleared, preventing memory accumulation over time.

Previously, after keygen completed, the Session page would just update the
status to 'completed' but not navigate away. Users had to manually click
the "Return Home" button. This could result in a white screen if the button
wasn't visible or clickable.
Now the page auto-navigates to home after 2 seconds, giving users time to
see the completion status and public key before redirecting.

When a party re-subscribes (e.g., Android reconnects), the old gRPC stream's
defer Unsubscribe() was accidentally removing the NEW subscription from the
subscribers map, causing the party to miss session_started events.
Fix:
- Subscribe() now returns the channel to the caller
- Unsubscribe() now takes the channel and only removes if it matches
- This prevents older streams from removing newer subscriptions

Problem:
- Android initiator/joiner could miss session_started events due to race condition
- Events arriving between joinSession() and _currentSession.value assignment were ignored
- This caused keygen timeout because parties never started the TSS protocol
Solution:
- Add pendingSessionId field set BEFORE joinSession() call
- Modify startSessionEventSubscription() to match events against both activeSession and pendingSessionId
- Clear pendingSessionId on session completion, failure, or cancellation
This ensures session_started events are correctly processed even if they arrive
before _currentSession is fully initialized.

Changed from single 2-second delay to 5 attempts at 500ms intervals.
This provides faster detection while covering a longer window (2.5 seconds total).
The polling loop:
- Checks every 500ms for up to 5 times
- Stops immediately if keygen is already triggered
- Stops if session context changes (user cancelled/navigated away)
This handles the case where the last joiner triggers session_started
but cannot receive the event themselves.

When multiple Android devices join a keygen session nearly simultaneously,
the last joiner may miss the session_started gRPC event because it's sent
before the device has fully set up its event subscription.
This fix adds a 2-second delayed polling check after join to detect if
the session has already started. If the session is in_progress and we
haven't started keygen yet, trigger it via polling instead of relying
solely on the session_started event.
