feat: add link to workspace from app error page

code-asher · code-asher · commit eb81af9de572 · 2025-12-01T10:01:06.000-09:00
When the workspace is stopped we show an error page if you try accessing
a Coder app.  Now it also includes a button to go to that workspace,
where you can start the workspace.
