formatting-insight-axes

Pick the right y-axis unit when creating or updating an insight via posthog:insight-create or posthog:insight-update — both TrendsQuery (trendsFilter.aggregationAxisFormat) and SQL insights (DataVisualizationNode, chartSettings.yAxis[].settings.formatting). Use when the agent is about to add a formula purely to convert units (e.g. dividing seconds by 60 to display minutes), when a math_property or SQL column is a duration, currency, ratio, or large count, or whenever the user mentions "format the y-axis", "duration", "seconds", "minutes", "hours", "milliseconds", "ms", "percentage", "%%", "currency", "decimals", "axis label", or "axis unit" in the context of a graph insight.
