DP bug — real cause found (client-side, not the DB):
loadSidebar builds a DM row for every contact you haven't messaged yet, but it copied only
{name, online} from the contact and DROPPED `avatar` (and status/email). So an un-messaged
contact always rendered initials in the 1:1, while the SAME person showed their photo in a
group (which reads /api/groups/members). Carry the whole contact through.
Kept a server-side safety net: avatarsFor() now indexes known photos under person-id, email
AND name, so a duplicate row missing a photo can match on any of them (the previous single
composite key missed twins with different emails).
Web updates are now completely silent: no banner, no toast. A web build is an implementation
detail — surfacing it makes users reason about "web build vs app version", which is exactly
the confusion to avoid. New code simply applies itself as soon as it's safe.
