Always show "View task" button for task workspaces #1292

Problem

On the Workspace page, the "View task" button (which links to /tasks/{owner}/{task_id}) is currently only rendered when the AppStatuses component is displayed. The AppStatuses component renders conditionally based on whether there are app statuses present:

1. AppStatuses returns null if allStatuses.length === 0 (source)
2. The "View task" button is a child of the AppStatuses component (source)

This means that for task workspaces where there are no app status updates, the "View task" button is never shown. The only indication that it's a task workspace is the label in the workspaces list.

Expected Behavior

The "View task" button should always be shown for task workspaces (i.e., when workspace.task_id is present), regardless of whether there are any app status updates.

This ensures:

• Users can always navigate to the task view from the workspace page
• There's a clear visual indication that the workspace is a task workspace

Proposed Solution

Move the "View task" button rendering outside of the AppStatuses component, or ensure it's rendered independently when workspace.task_id exists. The button could be placed:

• In the AgentRow component at a consistent location
• Or as a separate element that doesn't depend on the presence of app statuses

Relevant Code

• site/src/pages/WorkspacePage/AppStatuses.tsx - contains the "View task" button
• site/src/modules/resources/AgentRow.tsx - renders AppStatuses conditionally based on workspace.latest_app_status?.agent_id === agent.id
