Changed the SSH connectivity check failure message from a scary
"FAILED" warning with complex ProxyJump instructions to a simple
informational message.
Before:
- ⚠️ SSH connectivity FAILED for: ...
- Complex multi-line ProxyJump configuration
- Confusing for users who don't need temperature monitoring
After:
- ℹ️ Temperature monitoring will be available once SSH configured
- Simple list of pending nodes
- Brief note about pulse-sensor-proxy for LXC
- Link to docs for details
This makes the setup experience much more turnkey by reducing
noise and focusing on successful completion rather than optional
features that require additional configuration.
