Band Lineup 1.11.0: into the catalog, and to the guide's rules

The module arrived in the previous commit exactly as it runs in North
Attleboro. This brings it to the interface rules every module follows and
puts it where the admin page can offer it.

The three hide-toggles — names, mic labels, parallax — sat in a folded
"Show / hide" group. Rule 8 puts four or fewer at the top of the gear with
no group at all, so they are ungrouped and first; the Birthday group keeps
its switch. The test-mode select loses its help line (rule 5). Everything
else in the gear was already within the rules, and every title-bar control
was already an icon with a tooltip.

The Planning Center mock moves out of the module folder to tools/, beside
the other upstream mocks, so an install does not download a development
tool with the module; README and CLAUDE.md say how to run it. The version
goes to 1.11.0 so the copy already installed on NA is offered the update
from the repo, and the module joins the README's list.
