Hide Resolution Threshold on Chart When Using Automatic Resolution

This pull request updates the threshold visualization in useMetricDetectorThresholdSeries.tsx to prevent the resolution threshold shaded area from displaying on charts when the resolution is set to automatic. The logic now checks if the resolution value matches any of the alert threshold values, treating it as automatic in that case. Only manual resolutions (distinct from alert thresholds) will display the resolution line and safe area.

Key Changes

• Added an isResolutionManual check in useMetricDetectorThresholdSeries.tsx to determine if the resolution should be shown as a separate threshold.
• Modified logic for adding the resolution series and calculation of maxValue to only include the resolution value when isResolutionManual is true.
• Resolution threshold area is now hidden if resolution uses an automatic value (when its value matches any threshold).

Affected Areas

• static/app/views/detectors/hooks/useMetricDetectorThresholdSeries.tsx

Bug: Thresholds Disappear in Static Detection Charts

Alert threshold lines and areas are missing from charts for static detection types. This happens because the additional.push(...thresholdSeries); line, which adds these thresholds, was accidentally removed during changes to the resolution display logic.
