chore(repo): align sfu events naming with other SDKs

[Brazol]

Summary by CodeRabbit

• New Features

  • Added structured serialization for inbound video state notifications.
  • Centralized call, SFU, device, and WebRTC telemetry identifiers for more consistent diagnostics.

• Improvements

  • Standardized tracing across call lifecycle, reconnection, media, and signaling events without changing call behavior.

Warning

Review limit reached

@Brazol, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 57 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change centralizes tracing identifiers in TraceTag, replaces hardcoded trace strings across call, SFU, and WebRTC code, and adds JSON serialization for inbound video state events.

Changes

Trace tag migration and SFU event serialization

Layer / File(s)	Summary
Centralized trace tag contract packages/stream_video/lib/src/call/stats/trace_tag.dart	Defines shared constants for call, SFU, WebRTC, device, and media trace identifiers.
Call lifecycle instrumentation packages/stream_video/lib/src/call/call.dart, packages/stream_video/lib/src/call/session/call_session.dart, packages/stream_video/lib/src/call/stats/sfu_stats_reporter.dart	Replaces lifecycle and device-statistics trace strings with TraceTag constants while preserving payloads and control flow.
SFU tracing and event serialization packages/stream_video/lib/src/sfu/sfu_client.dart, packages/stream_video/lib/src/sfu/sfu_extensions.dart	Uses centralized tags for SFU RPC traces and adds JSON mappings for inbound video state notifications and states.
WebRTC and media instrumentation packages/stream_video/lib/src/webrtc/...	Replaces peer connection, media, device notifier, and factory trace strings with TraceTag constants.

76-91: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Inconsistent failure suffix: .failure vs .error

The SFU RPCs and createOffer/createAnswer use .failure for their error tags, while setRemoteDescription, setLocalDescription, and addIceCandidate use .error. Since this PR's stated goal is aligning naming conventions, consider standardizing on one suffix.

♻️ Suggested alignment to `.failure`

-  static const String setRemoteDescriptionError = 'setRemoteDescription.error';
+  static const String setRemoteDescriptionFailure = 'setRemoteDescription.failure';

-  static const String setLocalDescriptionError = 'setLocalDescription.error';
+  static const String setLocalDescriptionFailure = 'setLocalDescription.failure';

-  static const String addIceCandidateError = 'addIceCandidate.error';
+  static const String addIceCandidateFailure = 'addIceCandidate.failure';
