merge: keep fixed migration with correct compose_path column

Problem: linuxserver/code-server already binds to 0.0.0.0 by default.
Adding any command: override (--bind-addr or --host) breaks the LSIO
s6 init system with 'not found' errors.

Changes:
- _ensure_web_bind_address(): Skip LSIO images entirely (no command
  override needed). If an existing override is found, remove it.
- New migration 2026_05_29_remove_lsio_command_override: Removes
  --bind-addr and --host command overrides from both DB templates
  and existing instance compose files on disk for LSIO images.
- Fixed migration to use correct column name (compose_path) and
  check information_schema for column existence defensively.

Quality gates: ruff clean
