fix(ssh): use IP-style host placeholder

[arnestrickmann]

Summary

• Update the SSH connection host placeholder from a domain example to an IP-style example.
• Use documentation-range address 203.0.113.10 to avoid implying a real server.

Validation

• pnpm exec oxfmt --check apps/emdash-desktop/src/renderer/lib/components/add-ssh-conn-modal.tsx

Greptile Summary

This PR updates the SSH connection host field placeholder from "example.com" to "203.0.113.10", a documentation-reserved IP address from the RFC 5737 TEST-NET-3 block (203.0.113.0/24), which is guaranteed never to be assigned to a real host.

• The change is confined to a single placeholder prop in add-ssh-conn-modal.tsx, with no effect on validation, state, or submission logic.
• Using a TEST-NET-3 address is a sensible choice: it signals that IP addresses are a valid input format while ensuring the example cannot be mistaken for or accidentally resolve to a real server.

Confidence Score: 5/5

Safe to merge — the change touches only a UI placeholder string with no effect on connection logic, validation, or state.

The diff is a single-character string swap in a placeholder prop. No validation rules, form handlers, RPC calls, or SSH logic are touched, making regression risk negligible.

No files require special attention.
