ext.echo.alert: Restore orange background on Monobook

Core styles for Monobook include high-specificity background: transparent;
rule for #p-personal li a, we need to match it to set our background.

Also change hover behavior: switch to a deeper orange instead of
default white, similarly to how the badge already behaves.

Partially reverts I682182fe.
