When a pane cannot read something, it now says so

If the engine was busy when you opened AI Gateway, the Models tab used to say Reading the engine forever, and Providers showed grey placeholders under a red error. Now both show what went wrong with a Retry button. If only the model list failed to load, Models no longer tells you to connect an account, and it keeps the models and the System One choice it already had.

Connecting an account or changing a setting no longer says That did not work when the change went through and only the refresh afterwards was slow. It now says the change was made and the list could not be re-read. Usage no longer says Nothing recorded in this range when the real problem is that usage could not be read, and Brain no longer says there are no saved decision receipts when reading them failed. Memory shows its error with Retry instead of an error next to Reading memory forever.

Smaller fixes. A teammate's note in Memory is no longer a button that does nothing when clicked; hover it to read it. Undo on the setup toast now refreshes the Setup page so undone changes stop showing as applied. The phone guide button for the update step says Open Software Update instead of Open General. A Brain efficiency switch that fails to save shows its error right beside it. The helper model dropdowns no longer grey out for good after a save that Bandicot could not confirm.
