feat(doctor-report): GLP1 therapy section with titration + weight curve + side-effects

Phase 10 of W4d GLP-1 full integration. The doctor-report PDF gains a
dedicated "GLP-1 therapy" section when the patient has at least one
active GLP-1 medication and the existing compliance toggle is on. The
section lists what a prescribing clinician needs at every follow-up:

- Weight delta over the report window (start → end → delta)
- Per-medication block: drug name, current dose + start date,
  compliance count and rate, full titration history table
  (date | dose | note)
- Side-effect frequency table (last N days, counts per tag) when the
  mood section is also enabled (mood is the data source)

Generic accounts (no GLP-1 medication) get `glp1: null` from the
aggregator and the PDF skips the entire section, so existing reports
stay byte-identical.

Aggregator extension lives in `doctor-report-data.ts` — eager-loads
`doseChanges` + the most recent intake event on every active
medication (cheap, indexed); GLP-1 specifics only assemble when at
least one GLP-1 row exists. The field is optional on the type to
preserve compatibility with existing test fixtures.

DE + EN copy for the report section lives under `doctorReport.glp1*`.
