Add bulk log actions and status indicator to logs section in Workspace details page

MR: Pending

Description

To improve the workspace failure visibility & troubleshooting, we need to add bulk log actions at the footer and a status indicator at the header of the workspace logs section so that users can efficiently manage and export log data, and see current log status at a glance.

Visual Changes

Acceptance criteria

• Add "EXPAND ALL" button that expands all currently visible log entries
• Add "COPY" button that copies all log data based on current filter to clipboard
• Add "DOWNLOAD" button that downloads all filtered logs as a file (JSON or text format)
• Add current status indicator in logs section header (e.g., "Error" badge when errors are present)
• Implement proper loading states for download operation
• Show success feedback when copy/download operations complete
• Handle edge cases (no logs available, large datasets, network failures)
• Status indicator updates dynamically based on current log content
• All functionality integrates seamlessly with existing filtering and streaming features

TODO: Implementation plan

Notes

• Download logs: Download should include timestamp and workspace information in filename
