Admin: group ⓘ, group toggles in the title row, status readouts, Theme section

configGroups[name].help now renders as an ⓘ beside the group title (.group-info / .group-info-btn / .group-info-pop): a real labelled button — click pins a popover with the text, hover and focus peek at it, Escape or a click elsewhere closes it, and inside a collapsed group's <summary> it never folds the group. The paragraph above the fields is gone; per-field help stays one small line under its control.

configGroups[name].toggle names a switch/boolean field of the group: it moves into the title row, right-aligned (.field-group-toggle), as the group's on/off. While off the body dims to 0.45 (.field-group.is-off) but every field stays editable; the field is not repeated in the body, is saved exactly as before and still drives showWhen. Works with collapsed (the switch never folds the row) and columns. A toggle naming a non-boolean field is ignored.

The module card's status line is a .module-status readout: 1px --border, a background a shade lighter than the card, monospace, small radius and padding, with ok / connecting / error as the text (and border) colour.

New Theme section near the top: five swatches (.theme-swatch with a miniature bg/panel/accent preview), the current one marked, click POSTs /api/admin/theme and applies at once, errors show on a status line; other admin pages' changes arrive live over /api/events, and the login card already wears the server's theme.
