v1.46.1

Follow-up to v1.46.0's label family (#42, @LeeNX): the Web UI now makes label authority visible.

• A 🏷 marker appears wherever a docksentry.* label overrides the stored toggle, with a tooltip explaining that the compose file is in charge.
• The matching Pin/Auto toggle buttons are disabled while a label controls them — a click couldn't override the label, and an active-looking button that silently does nothing would be worse than an honest disabled one.
• The pinned badge now reflects docksentry.pin labels too.
