"""reset builtin download profiles: 720p is now the default (first) preset

Revision ID: 0058_dl_default_720p
Revises: 0057_plex_ppl_enriched
Create Date: 2026-07-22

The download dialog preselects the first builtin (lowest sort_order). Make 720p that default —
it plays everywhere, downloads faster, and is plenty for the shared /watch player — with 1080p and
Best still one click away. Re-seeds the builtin rows so fresh installs and existing DBs converge
(same mechanism as 0040). Existing jobs are unaffected (they snapshot their spec; a profile_id that
pointed at a replaced row just SET NULLs).
