Add interactive wizard for thv run command (#3050)

[carlos-gn]

Summary

• Add new --interactive / -i flag to thv run command that launches a step-by-step TUI wizard
• Implement 5-step guided flow: Server Source → Server Selection → Transport → Advanced Options → Preview
• Support 4 server sources: registry servers, container images, protocol schemes (uvx://, npx://, go://), and
  remote URLs
• Add searchable registry server list with fuzzy filtering
• Display command preview before execution for transparency and learning
• Support vim-style (j/k) and arrow key navigation throughout the wizard

Test plan

• Unit tests for wizard model state transitions and navigation
• Unit tests for command generation from wizard config
• Unit tests for server filtering and search functionality
• Unit tests for wizardConfigToRunFlags conversion (host, group, transport, image verification defaults)
• All existing tests pass

Closes #3050

Thanks for the PR @carlos-gn!
Seeing what this would look like in practice has made us realise that the maintenance of such a feature in the CLI would be quite high. With all the different flag options and combinations, this logic is better left to the desktop app.

I'm going to close this PR and the original spike.
Thanks for the work you've done here, it's brought a lot of clarity to the issue.

Hi @eleftherias I agree. No worries. Let me know if you want me to bring this to the app or work on something else with higher priority.

@carlos-gn This issue about persisting the dynamic OAuth client might be interesting to you #3335. Or let me know if something else catches your eye.
