Позиционирование как самостоятельного продукта и переход на AGPL-3.0-only

HY2XS больше не описывается как форк H UI. Из README, docs, сообщений
builder'а и post-install metadata убрана вся fork/H UI терминология.

Лицензия:
- LICENSE: MIT заменён на полный текст AGPL-3.0-only
- README: бейдж и раздел лицензии, подпись Flamy Studio
- orchestrator/package.json, apps/frontend/package.json: license
- package.sh: LICENSE кладётся в install package, license=AGPL-3.0-only
  в metadata
- verify.sh, acceptance.sh: проверки корневой AGPL и metadata

Документация:
- 04-admin-panel-h-ui-fork.md -> 04-admin-panel.md, переписан вокруг
  модели Hysteria2 = external runtime dependency,
  HY2XS admin = native HY2XS component
- docs 01, 02, 03, 08, 09, 11, 12, README: единая терминология HY2XS admin

post-install.env:
- блок HUI_* заменён на HY2XS_ADMIN_*, HUI_FORK_REF -> HY2XS_ADMIN_SOURCE

Внутренний legacy namespace (H_UI_* ключи SQLite, HUI_DATA/HUI_LOG,
API /hui, h_ui_db.sql) намеренно не тронут: он требует отдельной
миграции БД и выносится в отдельный этап.
