Add failed automation rerun action

[AmethystLiang]

Summary

• Adds a Rerun action for recoverable failed automation runs in the run detail view.
• Keeps a short pending state visible while rerun dispatch is in flight and refreshes automation runs afterward.
• Adds focused tests for recoverable rerun eligibility and pending visibility timing.

Design Doc

• docs/failed-automation-rerun-action.md

Validation

• Electron validation passed in round 2 for these scenarios:
  • dispatch failed recoverable run shows and triggers Rerun
  • pending click state is visible after clicking Rerun
  • non-recoverable run does not show Rerun
  • SSH recoverable skipped run shows Rerun
• Local reviewer screenshots are intentionally uncommitted under validation-screenshots/:
