Improve new agent wizard UX with tip box and header rename

- Rename wizard header from "Create a Maestro Agent" to "New Agent Wizard"
- Add info tip box explaining in-tab wizard alternative (/wizard command, wand button)
- Only show tip box when user has existing agents (first-time users won't see it)
- Update note copy: "The new agent wizard captures application inputs until complete"
- Add final sentence: "The in-tab wizard runs alongside your other work"
- Move "Select the provider" text directly above agent tiles
- Center note box vertically with equal spacing
- Update test mocks with sessions.getAll and sshRemote.getConfigs
