test: Add E2E tests for external dashboard APIs

[pulpdrew]

Closes HDX-3311

Summary

This PR adds E2E tests that verify that dashboards created and edited through the external API can be rendered correctly in the UI.

• The tests create a dashboard with all tile types through the external API, then assert that the tile edit form contains the correct values for all of the tile's properties.
• The tests verify that the dashboard can be saved from the UI, proving that the dashboard data conforms to the internal dashboard API's schema, after being created by the external dashboards API
• The tests also validate that dashboard updates and deletes via the external API are reflected in the UI.

PR Review: E2E Tests for External Dashboard APIs

✅ No critical issues found.

The implementation is well-structured with comprehensive test coverage for the external dashboard API. The code follows project conventions and includes proper error handling, type safety, and clear documentation.

Highlights:

• Good test organization with proper use of test.step() for clarity
• Comprehensive coverage of all chart types (time, number, table, search, markdown)
• Proper cleanup with unique dashboard names to avoid test conflicts
• Well-documented API helper functions
• Appropriate test tags for filtering (@full-stack, @api)

Minor observations (non-blocking):

• The verifyTileForm method is well-designed but could potentially be flaky if CodeMirror rendering is slow - the existing timeouts should handle this
• API helper error messages are clear and actionable
