feat(medications): show the GLP-1 drug-level estimate by default

Render the estimated drug-level-in-blood curve for any recognised GLP-1 medication without requiring the Research Mode opt-in. The chart still self-gates on a recognised brand and on having intake data, and the pharmacokinetic-estimate disclaimer is now always attached so the curve reads as a modelled value, not a measured blood concentration. Drop the now-dead Research-Mode gated-placeholder branch and its copy. The researchModeEnabled flag is unchanged; it still gates the advanced settings surface and its acknowledgment dialog.
