OnlineSched 3.8.0

OnlineSched 3.7.3

• Made favorite calendar subscriptions live and added subscriptions that retain the current schedule filters.
• Reworked schedule filters as accessible checkbox panels with independent room and tag selections.
• Added one authoritative tag-to-badge mapping screen and published every badge type carried by an event, including Sensory and ASL. Badge meanings remain stable when their labels change, and tags may be deliberately left without a badge.
• Added drag-and-drop room priority settings backed by stable room slugs and published the resulting order in the app feed.
• Kept map content out of the kiosk schedule introduction.
• Made matching revisioned Schedule, Hours, and Info app-feed URLs immutable. Stale revisions now return a non-cacheable conflict while legacy URLs retain their 60-second lifetime.
