Add Tailscale network support for host connections

Implement configurable network routing for both local and Tailscale networks.
Dashboard now supports intelligent connection selection with automatic fallback
between network types. Add IP configuration fields and connection routing logic
for ZMQ and SSH operations.

Features:
- Host configuration with local and Tailscale IP addresses
- Configurable connection types (local/tailscale/auto)
- Automatic fallback between network connections
- Updated ZMQ connection logic with retry support
- SSH command routing through configured IP addresses
