Various fixes: 2FA autofocus, viewer-timezone times, duplicate place guard (#1159)

* fix(auth): autofocus the 2FA code input when the MFA step appears (#767)

* fix(notifications): show notification and admin times in the viewer timezone (#1149)

SQLite CURRENT_TIMESTAMP is UTC but the string has no Z, so the client parsed
it as local time. Normalize in-app notification created_at to ISO-UTC, and stop
forcing the admin user table to render in the server timezone.

* fix(places): warn before adding a duplicate place (#1152)

Manually adding a place did not check the existing pool, so the same POI could
land in Unplanned twice. Flag a likely duplicate by Google Place ID, name or
near-identical coordinates and require a confirming second click to add anyway.
