feat: Add outbound egress metadata (IP + country) (#5886)

* Add outbound egress metadata

Show egress IP and country information for outbound HTTP tests. The probe reuses the temporary SOCKS route from the existing HTTP test and fetches Cloudflare trace metadata after the reachability check succeeds.

The outbound list now adds separate Egress and Country columns, hides egress IPs until the user reveals them, and marks Cloudflare WARP results with an orange cloud pill. Mobile cards keep the same data compact by placing the country and IPv4/IPv6 values on separate lines.

Validation: npm run typecheck; npm run lint; npm run build; go test ./internal/web/service/outbound

* Use context-aware DNS lookup for egress trace

* Address outbound egress review feedback

Restore the Real Delay selector and TCP default so the egress metadata change does not remove an existing test mode.

Keep HTTP probe tests hermetic by stubbing egress trace lookups, run IPv4 and IPv6 trace fetches concurrently with a shorter diagnostic timeout, scope mobile IP reveal state per row, support keyboard activation for reveal toggles, and treat WARP+ trace values as WARP-like.
