Finalization part 5

Short about the 5 new integration test files from yesterday:

• layout.test.ts tests the newly added props in Layout.astro

• sitenav.test.ts tests links and aria related current page information

• blog-index.test.ts testing an empty blog collection and a sorting test (will need to refactor this later since I plan to add sorting/filtering by tags for example)

• blog-routes.test.ts pretty selfexplanitory, it tests the blog post routing

• content.test.ts tests local blog post files, so that they follow the correct schema

• overall/other changes some of the above tests are guard-rails against sloppy coding/changing something that will break on current or other parts of the website. Like changing or misspelling a URL or prop. new config for vitest to make integration tests able to import and work. Also re-wrote all tests to use “test” instead of “it”, more or less because I prefer the clearer indication that it’s a test. These new tests also brought to light some redundant ones and methods + tests that did not work in the first place.
