BUG: TypeScript type errors in diary unit tests after sourceEntityTitle added to shared types

Severity: Major
Component: QA Integration Tests / Shared Types
Found in: CI Static Analysis job on PR #846

Steps to Reproduce

1. Open PR fix(diary): address 10 UAT feedback items for EPIC-13 (#836-#845) #846 on branch fix/836-845-diary-uat-fixes
2. Observe Static Analysis (typecheck) fails with TypeScript errors

Expected Behavior

TypeScript typecheck passes with 0 errors.

Actual Behavior

Multiple TypeScript errors in `client/` test files because the UAT fix (commit `91bc6fc`) added `sourceEntityTitle` as a required field to `DiaryEntrySummary` and `DiaryEntryDetail` types in `@cornerstone/shared`, but the QA integration test mock objects were not updated.

Affected files:

• `client/src/lib/diaryApi.test.ts` — mock objects missing `sourceEntityTitle` field
• `client/src/pages/DiaryEntryCreatePage/DiaryEntryCreatePage.test.tsx` — mock objects missing `sourceEntityTitle`
• `client/src/pages/DiaryEntryEditPage/DiaryEntryEditPage.test.tsx` — mock objects missing `sourceEntityTitle`

Error:
```
Property 'sourceEntityTitle' is missing in type '{ id: string; entryType: "daily_log"; ... }'
but required in type 'DiaryEntryDetail'.
```

Fix Required

Add `sourceEntityTitle: null` to all mock objects of type `DiaryEntrySummary` and `DiaryEntryDetail` in the affected test files.

Environment

• CI run: https://github.com/steilerDev/cornerstone/actions/runs/23112040243
• PR: fix(diary): address 10 UAT feedback items for EPIC-13 (#836-#845) #846
• Introduced by: commit `91bc6fc` (feat: implement 10 UAT fix issues fix(diary): Signature canvas rendering — dark mode, drawing offset, and sample rate #836-fix(diary): Remove PDF export and print functionality #845)

Notes

This is a qa-integration-tester responsibility. The E2E tests are not affected.

Resolved — sourceEntityTitle added to all diary test mocks during UAT fix rounds.
