iOS: Finances shortcut cannot be unpinned from the sidebar

What issue are you seeing?

In the ChatGPT iOS app, the Finances shortcut appears under the Pinned section in the sidebar, but it cannot be unpinned.

Long-pressing the Finances item does nothing. Normal pinned chats support pin/unpin management, so the Finances entry behaves differently even though it is shown in the same Pinned section.

I also removed/uninstalled the Finances plugin, but the Finances shortcut still remains in the Pinned section.

What steps can reproduce the bug?

1. Open the ChatGPT iOS app.
2. Open the sidebar.
3. Observe Finances under Pinned.
4. Long-press the Finances item.
5. No context menu or Unpin action appears.
6. Remove/uninstall the Finances plugin.
7. Return to the sidebar; the Finances shortcut is still pinned.

What is the expected behavior?

Finances should either:

• support Unpin / Hide from sidebar like other pinned items, or
• disappear from the Pinned section after Finances is removed/disabled.

Additional information

• Platform: iOS / ChatGPT mobile app
• The issue is specifically about the sidebar shortcut, not access to financial data.
• I can provide a screenshot showing Finances under the Pinned section if needed.

Start by reproducing the issue in the ChatGPT iOS app through the sidebar's Pinned section, following the listed long-press and plugin-removal steps. No source file or test is named; done means Finances can be unpinned or disappears after removal, with the existing pinned-chat behavior preserved.
