fix: treatments endpoint needs a created_at cursor, not date 699848b479

Investigated the "only ~4 days of treatments" report via direct
MongoDB access (issue #13): the collection has 123k+ documents, no
capping, no TTL index — the full year of history is in the database.

The actual cause: /api/v1/treatments.json filters/sorts on the string
field `created_at`, not the numeric `date` field /api/v1/entries uses.
Paginating with find[date][$lte] (or no filter at all) silently caps
treatments to an internal ~4-day window even though every document has
a valid `date` field; find[created_at][$lte] correctly walks back
through the full history.

_paginated_get() now takes an explicit cursor_field per endpoint and
always sends the cursor from the first request (never omitted), so
that hidden default window can't trigger. Verified against the real
instance: a 92-day treatments fetch now returns 39,403 rows (was ~700).
