The previous fix gave each point a unique x-axis timestamp so the tooltip could disambiguate same-day entries, but that caused real-time-scale spacing: transactions clustered minutes apart became impossible to click on individually. The desired behavior is equidistant slots for display, with the x value only needing to be unique for tooltip hit-testing. Switches the balance chart to a categorical x-axis keyed on the point's array index (computed on the frontend after fetching). The tick formatter looks up the date from the history array at that index so labels still show the calendar date. Each point occupies its own evenly-spaced slot and hover correctly identifies the specific point. The backend's now- unused `timestamp` field is removed.
