Wire up Update button for installed tools in frontend

[cmac86]

Summary

The installed tools view compares versions and has an Update button UI, but the onUpdate callback is never passed to the tool card/row components, so the button never renders.

What's already implemented

• Version comparison — getWorkflowStatus() in installed-tools-view.tsx compares caal_registry_version to registry version
• Update button UI — Both InstalledToolCard and InstalledToolRow render an orange "Update" button when onUpdate is provided and version mismatch exists
• Install/update API — /api/tools/install already handles re-installing over existing workflows
• Tool detail modal — Update button in the modal IS wired up via onInstall() and works correctly

What's missing

In installed-tools-view.tsx, onUpdate is not passed to InstalledToolRow or InstalledToolCard:

<InstalledToolRow
  key={workflow.id}
  workflow={workflow}
  status={getWorkflowStatus(workflow)}
  onShare={handleShare}
  onClick={handleRowClick}
  // onUpdate is NOT passed — button never renders
/>

Implementation

1. Add a handleUpdate callback in installed-tools-view.tsx that finds the matching registry tool and opens the tool detail modal (or install modal directly) with that tool
2. Pass onUpdate={handleUpdate} to both InstalledToolRow and InstalledToolCard
3. The existing install modal flow handles the rest (substitutes variables, creates workflow in n8n, activates, caches registry info, reloads tools)
