"""Legacy NULL-profile session owner backfill (#94724).
Pre-#95407 session rows carry ``profile_name = NULL``. Once a Desktop has
registry topology (≥2 registered connections) the fail-closed owner ladder
can no longer route those rows, making every pre-campaign session
unresumable. POST /api/sessions/owner-backfill stamps each store's own
serving-profile identity onto its legacy rows — single-match by construction
(a profile's state.db belongs to exactly one profile), idempotent, and never
overwriting a non-NULL owner.
