A new React unit test uses a non-standard matcher (toHaveBeenCalledExactlyOnceWith) that is likely to fail and should be replaced with supported Vitest/Jest assertions.

Pull request overview
This PR focuses on making date/time formatting and parsing culture-independent across the API and UIs, and adds tests to guard against regressions under non-default cultures.
Changes:
- Updated
UtcIso8601DateTimeOffsetConverter.Readto parse usingCultureInfo.InvariantCultureto avoid culture-dependent parsing. - Updated Blazor
Home.razortime formatting to use invariant culture and expanded related tests to cover multiple cultures. - Normalized the React API base URL by trimming trailing slashes and added unit tests to validate URL construction across base variants.

The updated React unit test file has an unclosed nested describe block, which will cause the test file to fail to parse/compile and/or unintentionally scope other tests.

🔵 Needs a closer look
It introduces/locks in ambiguous non-ISO date parsing expectations and includes generated dist/ build artifacts that make the change set noisy and harder to review/maintain.

tests/HackerNews.BestStories.Api.Tests/Serialization/UtcIso8601DateTimeOffsetConverterTests.cs:75
- The converter/test suite is asserting support for a non-ISO 8601 date format ("01/02/2025 03:04:05 +02:00"). Given the converter is named
UtcIso8601DateTimeOffsetConverter, locking in acceptance of ambiguous, culture-shaped formats makes the JSON contract less strict and the naming misleading. Prefer limiting test cases (and ideally parsing) to ISO 8601 forms only.

🟡 Changes recommended
The DateTimeOffset converter/tests currently permit non-ISO date inputs despite the documented ISO-8601 contract, and the PR also includes significant dist build output churn and unmentioned behavior changes that should be addressed/clarified.

🟢 Approval recommended
The changes are cohesive and low-risk, and they add/strengthen test coverage to validate culture-invariant behavior across the updated formatting/parsing paths.

🟡 Changes recommended
The converter’s quoted 'Z' formats can treat Z as a literal rather than a UTC designator, risking incorrect offsets depending on environment defaults.

Note
Low Risk
Localized date/time handling only; behavior is stricter on non-ISO JSON strings but aligned with the API’s intended format.
Overview
Makes API and Blazor story timestamps culture-independent so parsing and display stay correct on locales like
ar-SAorth-TH.UtcIso8601DateTimeOffsetConverterno longer uses culture-sensitiveDateTimeOffset.Parse; it accepts only explicit ISO-8601 patterns viaTryParseExactwithInvariantCultureand throws a clearFormatExceptionon invalid input. The Blazor home page’sFormatTimenow formats UTC strings withCultureInfo.InvariantCultureas well.Tests were broadened to run parsing, malformed-input, and rendered-time assertions under multiple cultures.
