Bug description

When creating a workspace from GitHub issues, the issue picker does not show all available issues for repositories with a large number of issues.

In one affected project there are about 560 GitHub issues, but only a subset is available in PolyScope, so many existing issues cannot be selected when creating a workspace.

This looks like the issue source is only partially loaded, likely because pagination or result limits are not handled in the picker.

Steps to reproduce

1. Connect a GitHub repository with a large number of issues (for example ~560 issues).
2. Start the flow to create a workspace from GitHub issues.
3. Open the issue picker or search for older issues that should exist.
4. Observe that only part of the repository issues is available.
