Chore(Ui): Fix flakiness in custom property playwrights

[aniketkatkar97]

This pull request updates the Playwright test suite for custom properties, focusing on improving test reliability and handling of custom property creation and advanced search scenarios. The most important changes include switching to timestamp-based property naming to avoid conflicts, updating API call handling for custom property creation, and improving page load synchronization in tests.

Test reliability improvements:

• Replaced the use of uuid() with Date.now() for generating custom property names in both Customproperties-part1.spec.ts and Customproperties-part2.spec.ts to ensure unique names and prevent conflicts during parallel test execution. [1] [2] [3] [4] [5] [6] [7] [8]

• Removed the unused uuid import from test files after switching to timestamp-based naming. [1] [2]

Advanced search and custom property creation enhancements:

• Updated the CustomPropertyDetails interface to support custom property configs with column lists, enabling more flexible property definitions.
• Refactored the advanced search test setup to sequentially execute API calls for custom property creation and directly assign created property data, avoiding issues with simultaneous requests and simplifying the data mapping logic.

Test synchronization and reliability improvements:

• Improved test synchronization by explicitly waiting for relevant API responses and selectors when verifying custom property persistence after a page reload, ensuring tests only proceed when the UI is ready.
• Replaced direct loader selector waits with the waitForAllLoadersToDisappear utility function for better reliability in entity panel navigation and summary panel opening. [1] [2] [3]

Code Review ✅ Approved

Clean, well-targeted test reliability fixes. The changes correctly address flaky test issues: replacing uuid with timestamp-based naming for ordering, adding proper Playwright API response waits before assertions, sequencing API calls to prevent server-side conflicts, and standardizing loader wait utilities. No bugs or concerns identified.
