The GLP-1 detail disclosure carried a titration block that only ever
rendered the standard EMA *reference* ladder — a static schedule with no
values from the user's own therapy, blank whenever the medication's brand
fell outside the catalog. Replace it with a dose-strength curve over the
user's recorded dose-change history.
The MedicationDoseChange stream is the history of record for titration
(2.5 -> 5 -> 7.5 mg escalation steps). The new curve plots that series as
a step line, carrying the latest dose forward to now so the current
strength anchors the right edge. With a single dose change there is no
escalation to draw, so the surface states the current dose plainly with a
"no titration history yet" caption rather than a flat single-point chart;
with none it shows the empty state. The curve plots only logged facts, so
unlike the estimated-PK drug-level chart it needs no Research-Mode gate.
Drop the now-unused reference-ladder section, its read route, the ladder
helpers, the titration query key, and the orphaned i18n block.
