feat: cancel dashboard queries when changing filters

[pauldambra]

covers hitting refresh while refreshing but not changing filters while refreshing

Problem

Dashboards can have expensive insight queries. users may change filters or get frustrated/distracted and navigate away. We don't cancel the queries, so ClickHouse does all of the work.

Changes

Adds insight query cancellation to dashboards

TODO

• verify this is really cancelling queries
• tidy it up 😊

punt to a follow-up

• changing filters currently waits for active refresh to finish and then loads the new set

How did you test this code?

🤷 I didn't yet 🤣

[pauldambra]

I'm still working on this. Needs more testing (so there are still console logs and things)

But this is mostly there so thought I'd for an early(ish) sense-check.

It feels that AbortController and the KILL backend route are begging to be coupled together somehow...

Perhaps we should have a KillLogic which receives the latest query id that got kicked off, supplies methodOptions and kills running queries via an action?
