The anesthesia record as chart data (ITE-1331, flag `AnesthesiaChart`): grid series on a real time axis, drug / fluid / milestone markers and phase bands. Built on read, like the phases, so a corrected time or a late grid edit shows on the next read; a finalized record reads the same way.

The anesthesia record as a chart (ITE-1331): numeric series from the monitoring grid on a real time axis, drug / fluid / milestone markers from the timeline, and phase bands from the shared phase resolver. Built by AnesthesiaChartProjection, which the console renders and the record export (a later ticket) is meant to share. Values are parsed once, server-side; a reading that doesn't parse, or a row that can't be dated, is left off rather than guessed.
