feat: add auto-refresh toggle wired to all polling queries

Upgrade @cameleer/design-system to ^0.1.3 which adds LIVE/PAUSED
toggle to TopBar backed by autoRefresh state in GlobalFilterProvider.

Add useRefreshInterval() hook that returns the polling interval when
auto-refresh is on, or false when paused. Wire it into all query
hooks that use refetchInterval (executions, catalog, agents, metrics,
admin database/opensearch).
