[Tech Debt] Add missing unit tests for ServerCleanupRoutine, PendingServerCleanupRoutine, and TerminateLongRunningServerRoutine

[sonikro]

Problem

Three of the six job routines in packages/entrypoints/src/jobs/ have no unit tests:

• ServerCleanupRoutine.ts — no test file
• PendingServerCleanupRoutine.ts — no test file
• TerminateLongRunningServerRoutine.ts — no test file

The other three routines (ConsumeCreditsRoutine, TerminateServersWithoutCreditRoutine, MonthlyUsageReportRoutine) all have test files.

Fix

Add test files for each missing routine. Each should:

• Use the makeSut pattern (no shared state)
• Follow Given/When/Then structure
• Mock node-schedule with vi.mock("node-schedule") (see ConsumeCreditsRoutine.test.ts for reference)
• Verify the job is scheduled with the correct cron expression
• Verify the use case is called when the job fires
• Verify errors are caught, logged via logger, and reported via eventLogger

Expected cron expressions to test:

• ServerCleanupRoutine: '* * * * *'
• PendingServerCleanupRoutine: '*/15 * * * *'
• TerminateLongRunningServerRoutine: '*/30 * * * *'
