Add Unit Tests for Session Service

[Mosas2000]

Description

The session service has no dedicated tests. backend/src/services/session.service.ts has no corresponding file in backend/tests/services/, so session creation and validation logic is untested.

Requirements and context

• Add a session.service.test.ts covering session flows
• Cover creation, validation, expiry, and revocation
• Use the existing test factories and helpers
• Ensure it runs under the unit vitest config

Suggested execution

Fork the repo and create a branch

git checkout -b test/session-service

Implement changes

• Add the test file
• Cover happy paths and edge cases
• Verify with npm run test:backend

Example commit message
