Lint: Unused variable in RlAnalyzer.php

[jjroelofs]

Description

The Drupal coding standards linter (phpcs) and PHPStan found issues in the analytics API code.

Issues Found

1. Unused variable (phpcs)

File: src/Service/RlAnalyzer.php:674

WARNING | Unused variable $center.

2. Dead catch blocks (PHPStan)

File: src/Drush/Commands/RlCommands.php

Lines 95, 141, 183, 216, 256 | Dead catch - InvalidArgumentException is never thrown in the try block.

3. Unnecessary null coalesce (PHPStan)

File: src/Service/RlAnalyzer.php:309

Offset 'rate' on array always exists and is not nullable.

Fix

• Remove unused $center variable
• Remove dead try-catch blocks (exceptions propagate naturally)
• Extract rate variables with proper empty array check
