bin: add set-home-layout.py — disable Next Up, ensure Continue Watching

Applied 2026-05-11 across both prod (13 users) and dev (1 user).
Replaces 'nextup' homesection slot with 'none' on every user; seeds 'resume'
at slot 0 for users whose CustomPrefs was empty (would have fallen back to
the Jellyfin factory default that includes Next Up).

Idempotent — re-running is a no-op once converged.

+"""
+Patch Jellyfin home-screen section layout for every user on a given instance.
+
+Default policy (this script):
+  - Continue Watching (`resume`)          ENABLED for every user
+  - Resume Audio       (`resumeaudio`)    preserved if present
+  - Next Up            (`nextup`)         DISABLED (replaced with `none`)
+  - Latest Media       (`latestmedia`)    preserved if present
+  - If a user's layout was empty (factory default), seed slot 0 with `resume`
+
+Idempotent. Safe to re-run.
