fix: resolve federation forward card showing zero flow (#212)

## Summary

Fixed federation port-forward tunnels not displaying traffic on forward
cards.

**Root Cause:**
- Frontend's mergeFederationShareFlow only parsed shareId from tunnel
name (Share-{id}-Port-{port} format)
- Federation tunnels with custom names couldn't be resolved, causing
traffic display to show 0

**Fix:**
- Added fallback to resolve shareId via remote-usage bindings[].tunnelId
- Multiple resolution candidates are merged with max(currentFlow)
selection
- Maintains directFlow precedence over federation share flow

**Tests:**
- Added contract test for custom tunnel name with binding-based
resolution
- All existing tests pass
- Frontend builds successfully

Fixes: federation port-forward showing total flow 0
