view_endpoint: fix error

[valentijnscholten]

Fixes #12295

The view endpoint page (used to view a host) was broken since #11952.

The problem is that the zip here cannot be set to be strict as the lists are deliberately created with different lengths. I believe this is done to be a "performant" way to pad the endpoints into num_cols columns. Any solution that could work with strict=True would have to determine the length of the queryset with endpoints. This could be considered inefficient for large querysets (even though maybe django just does a count() query). I believe we should just accept that this zip needs strict=False.

Added a UI test to prevent regressions. #12344 should prove that it fails if an error is present in the view_endpoint code.

This pull request involves a potential template rendering modification that could introduce unexpected behavior by allowing unequal list zipping, and includes some test file updates to expand test coverage.

💭 Unconfirmed Findings (2)

Vulnerability	Potential Unintended Behavior in Template Rendering
Description	Located in dojo/templatetags/display_tags.py, this change involves modifying the zip() function from strict=True to strict=False, which allows zipping of unequal lists. This could potentially cause unexpected rendering by padding with None values, leading to visual or logical template inconsistencies.

Vulnerability	Test File Modifications
Description	Changes in tests/endpoint_test.py appear to be focused on expanding test coverage. No direct security vulnerabilities were detected in these modifications.
