Release v1.2.0

Release 1.2.0: optional Doctrine profile overrides and admin CRUD

Changelog

Added

• Optional Doctrine profile storage: use_database_config + doctrine.table_prefix.
• Entity QrCodeProfileConfig (table qr_code_profile); DB rows with the same name fully override YAML profiles; DB-only names are also resolvable.
• Admin CRUD at /admin/qr-code-profiles (import from YAML, create/edit/delete) with role gate via security.access_roles.
• Flex recipe routes import (config/routes/nowo_qr_code.yaml) for the admin CRUD.
• Composer suggest entries for doctrine/orm, doctrine/doctrine-bundle, symfony/form, symfony/validator, and symfony/security-bundle.

Upgrade: leave use_database_config: false (default) for no change. See UPGRADING.md.
