Fix PostgreSQL connection leak in test environment

[Copilot]

Job tests were causing PostgreSQL connection leaks in CI, failing with 583 test failures due to exhausted connections.

Root Cause

The application uses GoodJob as the ActiveJob adapter globally. GoodJob maintains a separate database connection pool that persists across inline job executions in tests, preventing proper connection cleanup.

Changes

• Configure test environment to use Rails' :test adapter instead of GoodJob
• Add config.active_job.queue_adapter = :test to config/environments/test.rb

The :test adapter executes jobs inline without a separate connection pool, ensuring connections are properly returned after each test.
