fix(tests): EventListenersTest must extend package TestCase

EventListenersTest was extending Orchestra\Testbench\TestCase
directly instead of our PHPeek\LaravelQueueMetrics\Tests\TestCase.

This caused:
1. Tests to bypass our getEnvironmentSetUp() that disables metrics
2. defineEnvironment() to enable metrics without Redis check
3. Tests to attempt Redis connection even without REDIS_AVAILABLE
4. Connection refused errors when running without Redis service

Changes:
- Use PHPeek\LaravelQueueMetrics\Tests\TestCase as base class
- Call parent::defineEnvironment() to inherit config disabling
- Remove duplicate getPackageProviders() (inherited from base)
- Tests now properly skip when REDIS_AVAILABLE env var not set

Result:
- 124 tests pass with --exclude-group=redis,arch (was 118)
- No Redis connection errors when running without Redis
- EventListenersTest properly skips all 3 tests without Redis
