FX.18 Developers page: Make a key redesigned, form errors now show

Owner 2026-11-04 sent a screenshot of /account/developers. The form was a narrow column with a long flat list of permissions. Now it fills the section, permissions are a table of areas by See and Change with the scope name in small text, Data choices sit side by side, and Workspace, Expires and Allowed addresses are grouped as Limits. The API keys section gets a docs button and a link to the first key. Bug fixed: after the Name field the form lost its form id, so a missing permission or a bad address said 'Check the highlighted fields' with nothing highlighted, and Workspace, Expires and Allowed addresses were lost. Checked with a real live key on a test account: bad input, make, show once, revoke; desktop and phone, Paper and Model. Sandbox keys could not be checked: the sandbox is not open.
