Port of Feature 04 task 3 (7629cab) onto Feature 04 + Feature 03.
On first boot create the single household_settings row with the zone from
MEALQUEST_DEFAULT_TZ and the seed times and days (dinner 17:30, reminder
16:30, rotation check 09:00, plan draft Fri 09:00, suggestions Sun 08:00,
chat autosend Sat 08:00). An existing row is never overwritten.
Add household.SettingsService with Get, a validating Update (IANA zone,
zero-padded 24-hour HH:MM, day of week 0-6) that records updated_by, and
in-process Subscribe for the scheduler. Serve it as GET and PATCH
/api/v1/settings/household; invalid input is a 400 in the standard error
body. Migration 0002 adds household_settings.updated_by. Link time/tzdata
from internal/household so zones load in the minimal image.
Review fixes:
- F1: the settings routes are mounted on the protected /api/v1 subrouter,
so they need a session (RequireSession) and, for PATCH, the CSRF token.
updated_by is the session actor's subject from auth.ActorFrom; the
duplicate internal/actor package is dropped, and Update refuses an empty
member instead of storing NULL. A test drives PATCH through the
production router with a real SessionManager session.
- F2: config no longer validates MEALQUEST_DEFAULT_TZ. Seeding requires a
valid zone only when it creates the row (ErrNoDefaultZone,
ErrInvalidDefaultZone, both naming the variable at boot), so a reboot
over existing settings ignores a missing or invalid default.
