fix: fix Arma 3 log discovery and improve config editor UX

- Fix logfiles_router and thread_registry to resolve .rpt log files
  from Path(server["exe_path"]).parent/server/ instead of the languard
  data dir, which never contained log files — log list and live tail
  both now work correctly
- Rewrite get_ui_schema() in config_generator to cover all ~80 fields
  across all 5 sections (server/basic/profile/launch/rcon) with proper
  toggle/select/number/password/tag-list/hidden widgets and labels;
  missions field is hidden (managed by Missions tab)
- Add formatSelectDisplay() to ConfigEditor so select fields show
  descriptive text (e.g. "0 - Never") instead of raw numbers in view mode
- Add ToggleDisplay for boolean fields (Enabled/Disabled with indicator dot)
- Add section tab labels and descriptions to ConfigEditor
- Add MissionList UX hints and dynamic Add/In Rotation button labels
- Add "hidden" to FieldSchema widget union type
- Update API.md, ARCHITECTURE.md, CLAUDE.md, FRONTEND.md, MODULES.md,
  THREADING.md to document log path fix and schema coverage
