Realtime dashboard improvements (#2445) * add a new realtime-update-timer module * hook to the new 'tick' event in ListReport for auto-updates This commit fixes the bug where all reports using the `ListReport` component did not auto-update in realtime mode. Those reports are: - Pages (Top / Entry / Exit) - Locations (Countries / Regions / Cities) - Devices (Screen Sizes / Browsers + versions / OS-s + versions) * fetch data for ListReports only when scrolled into view * refactor fetching data in ListReport * refer to one source of truth for utm tags * make the 'All' tab in Sources auto-update * make all UTM tabs in Sources auto-update * fetch UTM data only when scrolled into view * auto-update Referrers with the new timer * auto-update google search terms * auto-update Conversions * make countries map auto-update * auto-update visitor-graph and top stats with new timer * use new tick event for current visitors (in Historical) * remove the old timer class * update changelog * Visual improvements to automatic realtime updates (#2532) * minor consistency fix for text color in dark mode * use FlipMove in goal conversions report * use FlipMove in ListReports * set main graph and top stats loading state correctly * refactor isIntervalValid function * enforce intervals are valid when set and stored * remove duplicate data fetching on interval change Fetching new data is handled by the `fetchGraphData` callback in `updateInterval` * refactor updateMetric function * make it clearer why 'metric' can be a faulty value * extract 'query' and 'site' variables from 'this.props' * reset interval state only when period is changed The 'maybeRollbackInterval' function was also used to fetch data. This commit replaces all those function calls with 'fetchGraphData' which better describes the actual behavior. We should only worry about rolling back the interval if 'query.period' has changed. This commit also stops the graph from flickering when it is updated in realtime. * update names of two variables * remove unnecessary negation * make collapsed graph state more explicit * consider stored invalid intervals when graph mounts * fix not showing loading spinner regression * remove interval state from VisitorGraph (#2540) * Realtime prop breakdown (#2535) * disable load more in realtime mode * extract doFetch function * separate fetchPropBreakdown and fetchNextPage functions * subscribe for auto-updates in realtime * improve readability with function name changes 2023-01-02 18:42:57 +03:00			`const THIRTY_SECONDS = 30000`
