Change auto connection type to prioritize local IP first

Update the auto connection type logic to try local network connections
before falling back to Tailscale. This provides better performance by
using faster local connections when available while maintaining Tailscale
as a reliable fallback.

Changes:
- Auto connection priority: local → tailscale → hostname (was tailscale → local)
- Fallback retry order updated to match new priority
- Supports omitting IP field in config for hosts without static local IP
