fix(cloud-tests): move remediation preview to Trigger.dev

[tofikwest]

Summary

The "Preparing fix plan" step (preview) runs 3+ LLM calls + cloud API reads + permission analysis, often taking 50-70+ seconds — exceeding browser timeout limits and causing silent failures ("Failed to load preview").

Now both preview AND execute run as Trigger.dev background tasks with real-time progress via websocket. Zero browser timeout risk for the entire remediation flow.

Changes

File	What
remediate-preview.ts (new)	Trigger.dev task — calls /v1/cloud-security/remediation/preview via service token, streams result via metadata
single-fix.ts (action)	Added startPreview() server action (same pattern as startSingleFix)
RemediationDialog.tsx	Two separate useRealtimeRun hooks: one for preview, one for execute. Removed all synchronous api.post calls.

What changed for the user

Nothing visible — same UI, same loading animation, same preview display. The only difference is it won't silently fail after 60 seconds.

Edge cases

• Guided-only mode — unchanged, no API call needed (local data)
• Permission recheck — also runs through Trigger.dev (passes cachedPermissions to skip AI re-analysis)
• Dialog close during preview — task continues, state cleans up on reopen
• Preview task failure — shows error message (same as before)

Test plan

• Open Fix dialog for a finding → "Preparing fix plan" animation shows → preview loads via Trigger.dev → current/proposed state displayed
• Click Apply Fix → executes via Trigger.dev → success shown
• Preview with missing permissions → permission panel shown → Recheck button works (also via Trigger.dev)
• Guided-only findings → manual steps shown without any API call
• Close dialog during preview → reopen → fresh preview starts

Summary by cubic

Move the remediation preview to a @trigger.dev background task with real-time progress to eliminate browser timeout failures during “Preparing fix plan.” Preview and execute now follow the same async task pattern.

• Refactors
  • Added remediate-preview Trigger.dev task (3-minute max) calling /v1/cloud-security/remediation/preview with a service token and streaming progress via metadata.
  • Introduced startPreview() server action in single-fix.ts that returns a run ID and public token via @trigger.dev/sdk.
  • Updated RemediationDialog to use separate useRealtimeRun hooks for preview and execute (@trigger.dev/react-hooks), removed direct api.post calls, and routed rechecks with cachedPermissions through Trigger.dev.
  • No UI changes; long previews no longer fail silently, and tasks continue if the dialog is closed.

_{Requires human review: This is a significant architectural refactor that moves a core feature (remediation preview) to background tasks, requiring human verification of the new async flow.}
