[Test Improver] tests: add unit tests for useUserRetentionValidation composable

[github-actions]

🤖 This PR was created by Test Improver, an automated AI assistant focused on improving test coverage.

Goal and Rationale

Add unit tests for shell/composables/useUserRetentionValidation.ts, a composable containing user retention validation logic with multiple branches and edge cases — previously at 0% coverage.

This composable validates:

• Cron expressions for scheduled user retention jobs
• Duration strings for disabling/deleting inactive users
• Minimum duration enforcement (336h)
• Duration comparisons against the auth user session TTL

Approach

• Mocked useI18n and vuex to isolate pure validation logic
• Used a makeComposable() helper to construct the composable with reactive refs
• Split it.each tables into separate pass/fail blocks to comply with jest/no-conditional-expect ESLint rule
• Covered boundary conditions (exactly 336h), null inputs, empty strings, and the regex quirk in parseDuration (alternation without full anchoring matches leading unit in multi-unit strings)

Coverage Impact

Metric	Before	After
Statements	0%	97.4%
Branches	0%	89.5%
Functions	0%	100%

Test Status

✅ 27 tests pass
✅ ESLint clean (--max-warnings 0)

Reproducing

node_modules/.bin/jest --no-coverage shell/composables/__tests__/useUserRetentionValidation.test.ts
