feat(swqos): Astralane QUIC region-based endpoints and endpoint selection

- Add SWQOS_ENDPOINTS_ASTRALANE_QUIC array (8 regions: ny, fr, ams, lim, sg, ams, la, lim)
- Select QUIC endpoint by region and optional custom URL in get_swqos_client (was hardcoded)
- Use primary endpoints only; avoid ams2/fr2 for lower latency
- Align with Astralane QUIC docs (port 7000, gateway.astralane.io)
