Server query extended with MAX(BU_BU) per user as LAST_STAMP,
exposed via the Availability model. Client formats it as
DD.MM. HH:mm next to the loggedIn dot, replacing the mocked time.
New Availability module decorates each people-tile with a vertical
status bar on the avatar and a dot+timestamp under the status text,
showing ZeitConsens loggedIn state per extension.
Status and Availability now share a single AvailabilityService that
polls /availability every 30s, halving the API load. Avatars are
enlarged to 57px and vertically centered to fit the new layout.
