Follow up work for cache UI

Beta Give feedback

1. Measure minimum query duration in seconds (In Admin > Performance, display minimum query duration in seconds #40970)
2. Change default minimum query duration to 1 second (not 60 seconds) (In Admin > Performance, display minimum query duration in seconds #40970)
3. Add 'Invalidate now' button ([Cache] Add "Invalidate cache now" button #40972)
4. Move Invalidate now button to the top of the form along with the name of the database ([Cache] Add "Invalidate cache now" button #40972)
5. Create DelayedSpinner component (Use DelayedLoadingAndErrorWrapper component in Admin > Performance #41103)
6. Add e2e tests. This will be complicated, since our test of the old cache invalidation UI was disabled due to a bug
7. Ensure that form fields can be tabbed into even when behind form buttons div (I have this in a branch but I'm not sure it's worth pursuing)
8. Rename TTL to Multiplier
9. [not planned] Tweak: remove value from inputs (and just show placeholder) if it matches the default (and ensure form dirty status is correct)
10. Polish: delay all spinners by 300 ms
11. Try Ryan's suggestion to avoid the useVerticallyOverflows hook (https://app.graphite.dev/github/pr/metabase/metabase/39234/Basic-cache-admin-UI?utm_source=gt-slack-notif#comment-PRRC_kwDOAczgH85cTMwl)
12. Explore Ryan's suggestion to use different forms for different strategies (https://app.graphite.dev/github/pr/metabase/metabase/39234/Basic-cache-admin-UI?utm_source=gt-slack-notif#comment-PRRC_kwDOAczgH85cTRiE)
13. Put Cache Upsell component on OSS page #41119
