feat(slo): burn rate rule editor

[kdelemme]

📝 Summary

Related to #145262

This PR creates the burn rate rule editor form, with the different components and validation required.

The LongWindowDuration component validates that the duration is at least 30minutes and no more than 24 hours or 1440 minutes.
When an SLO is selected and the longWindowDuration is changed, the component computes the max burn rate allowed as defined by slo_window_in_minutes / long_window_in_minutes.

This PR does not integrate the Editor with the Rule framework yet. To prevent this PR to grow too much, I'll do the integration in a followup PR.

• Searching on "Select SLO" doesn't filter the list on user input.

• When I type . in "Burn rate threshold", the value clears out to 0. Is this expected behaviour?

Searching on "Select SLO" doesn't filter the list on user input.

This one is tricky since the Storybook uses mocks for the hook, therefore whatever you type always returns the same data. We would need to test with real data when we create the rule but this will be done in another PR.

When I type . in "Burn rate threshold", the value clears out to 0. Is this expected behaviour?

Good catch, the value needed to be set as a string actually 😬

LGTM!
