Improve Messages display and add new message parameter types across all drafts

Further improve processing to reduce impact of instrumentation on multiple concurrent connections.

Performance improvements to background rendering on active connections.

Added support for concurrent WebTransport connections.

Worker wrapping now uses a Proxy-based recovery system that automatically detects CSP failures, transparently falls back to the original uninstrumented Worker, and remembers the origin for future visits.

ISO BMFF media detection & hex viewer annotations

• Proper ISO BMFF box parser replacing heuristic byte scanning
• Classifies payloads as CMAF, LOC, or fMP4 based on box types and brand codes
• Streams list shows variant + box count (e.g., CMAF(3)) with box names in tooltip
• Hex viewer renders inline boundary banners between objects with content description and offset indicator
• Object navigation (‹ 1/5 ›) in sticky bar for streams with 2+ objects
• Detection retry on subsequent chunks when first chunk arrives before draft detection

Control stream identification

• Bidirectional MoQT control stream correctly labeled "MoQT Control" instead of inheriting a track name
• Control stream preserved when clearing stream data (always-open, unrecoverable)

Track list: faster navigation
- New filters on Messages/Tracks: Active only, TX/RX, and Group by namespace (collapsible with status counts).
- Filters persist between tab switches and browser sessions.

Streams tab: usable at scale
- Added a search box to filter streams by track/namespace.
- Added a stats footer showing stream count + total TX/RX bytes, including filtered vs total when a filter is active.

Better control over captured data
- New recording toggle: pause stream data capture without losing control messages / track lifecycle.
- New clear button: wipes all captured stream data and frees memory/storage instantly.

Reliability fix: no more dropped control messages
- Fixed decoding so all control messages in a chunk are processed (not just the first).
- Added buffering so control messages split across chunks are reassembled correctly.

Performance improvements (large sessions)
- Streams list now uses virtual scrolling (renders only visible rows).
- Reduced repeated work across stream/track/session stats computation.

UI cleanup
- More compact track header layout.
- Better panel alignment.
- Standardized DevTools-style clear icons.

Added stack trace capture for outgoing control messages and unidirectional stream creation. A new "Stack" tab in the message detail panel shows the application call stack with clickable source links and async boundary grouping.
