Add CLI command for setting up states/regions for additional countries

[Copilot]

Only Austria (AT) and its states are created during installation. Additional countries/states require manual maintenance, creating high effort and error-prone configuration in multi-market setups.

Changes

• New command coreshop:setup:states: Creates states/regions for specified countries using existing Rinvex country data
  • Accepts comma-separated ISO codes
  • Skips existing states to prevent duplicates
  • Optional --activate-country flag to activate inactive countries
• Service registration in commands.yml
• Documentation added to States section

Usage

# Single country
php bin/console coreshop:setup:states DE

# Multiple countries with activation
php bin/console coreshop:setup:states DE,US,FR --activate-country

The implementation follows the same patterns used in CountryFixture.php for consistency.

<issue_title>Missing Migrations / Commands for Additional Markets</issue_title>
<issue_description>Problem Statement
The creation of additional markets and their corresponding states/regions is not automated.

Description

• During installation, only AT (Austria) and Austrian states are created by default.
• Additional countries or states must be maintained manually.
• There is no migration or CLI command available to initialize further markets.

Impact

• High manual effort in multi-market setups.
• Error-prone manual configuration.

Mitigation

• Provide a CLI command (e.g. coreshop:setup:states).
• Alternatively, provide configurable migrations for countries/states.
• Alternatively, allow markets to be defined declaratively (e.g. YAML/config) and created automatically.
