Consolidate duplicated `generateMockToken` helper into shared test/story utility

[sourcery-ai]

Summary

The generateMockToken helper is currently duplicated across multiple story files (e.g., apollo-connection.stories.tsx and at least one other story). This duplication can lead to divergence in behavior over time and makes maintenance more difficult.

This issue proposes consolidating the generateMockToken logic into a single shared test/story utility and updating all story files to use that shared helper.

Current Behavior

• Multiple Storybook stories define their own generateMockToken helper locally.
• Implementations are very similar/identical but live in separate files.
• Any future change in token generation would need to be updated in multiple places, with a risk of inconsistencies.

Proposed Solution

1. Create a shared helper file for mock token generation, for example:

   • apps/ui-sharethrift/src/test-utils/mockToken.ts

   With the following implementation (as suggested by Sourcery):

   export const generateMockToken = () => {
     const randomPart = Math.random().toString(36).substring(2, 15);
     const timestamp = Date.now().toString(36);
     return `mock_${timestamp}_${randomPart}`;
   };

2. Update stories to use the shared helper

   • In apollo-connection.stories.tsx and any other story files that currently define a local generateMockToken, remove the local function implementation.
   • Import the shared helper instead, adjusting the path to match the repo’s structure and alias conventions:

   import { generateMockToken } from './test-utils/mockToken';
   // or, depending on project structure
   // import { generateMockToken } from '../test-utils/mockToken';
   // or
   // import { generateMockToken } from '@test-utils/mockToken';

3. Refactor usage

   • Replace all references to the local generateMockToken functions with the imported helper.
   • Ensure that stories still work as expected (run Storybook and/or tests involving these stories).

Acceptance Criteria

• A shared generateMockToken helper exists in an agreed-upon test-utils or shared stories utilities location.
• All stories that previously defined their own generateMockToken now import and use the shared helper.
• Storybook runs successfully and all relevant stories still render/function correctly.
• No remaining duplicate generateMockToken implementations in the codebase.

Notes

• This is a refactoring/cleanup task and was explicitly called out as out of scope for the Snyk implementation work, so it should be handled separately from that feature.
• Maintain consistency with existing project conventions for test/story utilities (directory structure, import aliases, etc.).
