--mauve is not declared in base.css; the palette exposes the Catppuccin
Mocha mauve colour as --purple (#cba6f7). Affected rules:
.btn-move colour + border
.logs-back colour (back-link on logs page)
.logs-tab.logs-tab-active text colour (issue #1001 — tab shows no state)
border colour on a schedule input
Combined with the --surface1/2 fix from the previous commit, the active
log tab now shows a solid background (--border) with purple text (--purple).
