Marc-André Bombeck a14174fe4d Let a medication have several courses
A medication taken now and then (#1024) keeps one row and gains course
rows: calendar spans, both ends inclusive, an optional encrypted note, no
schedule or dose of their own. Courses never overlap and every course but
the latest has ended, so the latest course is always the one the
medication's startsOn/endsOn project. src/lib/medications/courses.ts is
the only writer of those two columns for a medication with courses; it
writes under a per-medication advisory lock and re-projects in the same
transaction, so reminders, the next-due line and intakeActionable keep
reading the columns and stay right.

- Migration 0368 adds medication_courses and backfills one course per
  medication window (an end-only window starts on the creation day, or
  on its end day when that lies earlier); a medication without a window
  stays course-less. Idempotent, data-preserving.
- GET/POST /api/medications/{id}/courses and PATCH/DELETE
  .../courses/{courseId} (owner-only); create seeds the first course
  from a window; the medication PUT edits the latest course and refuses
  a window that would break the rules (medications.course.*).
- List, detail, create and update carry courses, courseCount,
  previousCourseEndedOn and canStartCourse, resolved on the server.
- Compliance expands over the span of all courses and drops the slots
  between them; every compliance read selects the courses. A rolling
  cadence is not anchored by an intake from a previous course.
- The card names the last course's end and the running course's number;
  the detail Lifecycle group lists the courses with start, edit and
  delete. The Coach compliance block, the MCP resource, the doctor
  report window and table, the clinician view and FHIR (one
  MedicationStatement per course with effectivePeriod and status) read
  the courses.
- Backup carries courses per medication and the restore writes them and
  re-projects; an older file derives the one course its window
  describes. Wipe plan, encrypted columns, rotation and OpenAPI follow.
