A failing account's error ("sign-in required … press L to run az login --tenant …") stayed in the footer for the whole session.
- **Footer:** it's now an ordinary message, shown once when an account's error first appears (at start, or when a load fails), and gone on the next key press. It's said again only when the errors change, or for another account.
- **Details:** with that account's group header or one of its sources selected, the Details pane shows the error and the sign-in hint, in place of "Select a vault or scope…".
- **`L`** signs in to the selected account when it needs it, else to the last one that asked, as before. With two accounts, `L` used to run whichever sign-in had failed most recently.
Test: two accounts, one failing to list its subscriptions. The message is in the footer at start and gone after a key press, in Details on that account's group, and `L` targets it. It isn't shown on the other account's rows.
