  back to default_mission_params, then omits entirely if both empty
- Add key-value widget to ConfigEditor for default_mission_params field
- Add MissionParamsEditor component for editing param key/value/type rows
- Bump config schema to 1.1.0 with migration from 1.0.0
- Add normalize_section() to Protocol and ArmaConfigGenerator for
  read-time backfill of old stored rows
- Set Arma3 BasicConfig and ProfileConfig defaults from basic.cfg /
  Administrator.Arma3Profile
- Document 3 known Mods tab bugs in CLAUDE.md for next-session fix
