When a medication's start date or interval changes, the generated dose
IDs shift (dateOnlyMs values change). Previously, doses marked as taken
under the old schedule were orphaned — they no longer matched the new
schedule's dose IDs, causing them to appear as missed.
Now the PUT /medications/:id endpoint:
1. Parses old intakes from the existing medication row
2. Detects which intake indices had schedule changes
3. Maps old dateOnlyMs values to the nearest new dateOnlyMs
4. Updates dose_tracking entries with the migrated IDs
5. Preserves person suffixes (e.g. -Alice) during migration
Also fixes the start-date cleanup to use date-only comparison,
preventing doses on the start date from being incorrectly deleted
when the start time is after midnight.
Adds 4 integration tests covering weekly day shift, person suffix
preservation, time-only changes, and interval changes.
