[aditisb1212-lab]

Plugin History UI

Summary

This PR adds a Plugin History panel to the Plugins section, allowing users to view and inspect previous plugin executions. The history includes filtering, execution status, timestamps, and expandable input/output details to improve auditing and debugging.

Changes Made

Frontend

• Added a Plugin History section to the Plugins panel.

• Displayed plugin execution history with:

  • Plugin name
  • Input (truncated)
  • Output (truncated)
  • Timestamp
  • Success/Failure status

• Added filtering by:

  • Plugin name
  • Date range (start date and end date)

• Added expandable Show More / Show Less functionality to view complete input and output.

• Improved accessibility by adding aria-label attributes to filter inputs.

• Updated SQLite timestamp parsing to ISO UTC format for consistent date filtering across browsers.

Backend

• Extended plugin execution logging to record both successful and failed plugin executions.
• Improved plugin log retrieval to support filtering.
• Fixed exception handling and indentation issues in the plugin execution route to ensure reliable error logging.

Expected Behavior

• Users can view the history of previously executed plugins.
• Users can filter history by plugin name and date range.
• Each history entry displays execution status, timestamp, input, and output.
• Clicking Show More expands the full input and output.
• Failed plugin executions are also logged for better debugging.

Testing

• Verified plugin execution history is displayed correctly.
• Verified plugin name filtering.
• Verified date range filtering.
• Verified success and failure status indicators.
• Verified expandable input/output.
• Verified timestamps display correctly after SQLite timestamp conversion.
• Verified plugin history refreshes after running a plugin.

Closes #482

"Approved. Functionally it's perfect. Just a couple of optional nits (variable naming/formatting) – feel free to address them in a follow-up PR if you want. Merging this now."
