Tasks: "View Prompt" button should be a visible button, not hover-only #21651

Description

In the Tasks UI, the "View Prompt" action requires hovering to reveal it, while "Share" and "Go to Workspace" are visible buttons. This inconsistency makes discoverability poor.

Current Behavior

• "View Prompt" only appears on hover
• "Share" and "Go to Workspace" are always visible as buttons

Proposed Solution

Make "View Prompt" a visible button using the same style as "Open Ports" on the workspace view:

This provides consistent button styling and improves discoverability of the prompt viewing functionality.

Acceptance Criteria

• "View Prompt" is a visible button (not hover-only)
• Button style matches "Open Ports" or similar existing patterns
• Consistent with other action buttons in the Tasks UI
