chore(release): v1.33.1 — what the app knew and did not say

Eight workstreams, two migrations, and a pass by an independent reader that
found four things this release was claiming about itself that were not true.

Two of the fixes change what people receive. Medication reminders went out
every fifteen minutes because the dedup key could not tell one dose slot from
another, and "handled by the app" was silencing every channel rather than the
one it names. Both are called out in the notes, because a user who set that
flag as a general mute will notice.

Two came from reports: an OpenAI-compatible gateway that the provider list
had no room for, after an earlier answer from us said otherwise, and four
places where a timestamp followed the browser instead of the profile.

The backup half is the one worth reading. Three record types were carried and
could not be restored, or could not be carried at all, and each failed in a
different direction: one dropped silently, one stopped the restore outright,
one was discarded while the restore reported success. What a backup holds is
now declared in one file with a written reason for everything left out, and
the roughly thirty types that are still carried by neither end are named there
instead of waiting to be discovered by someone who needed them.
