feat(e2e): migrate unlinked page tests to playwright

[seaerchin]

Problem

Previously, the tests for editing of unlinked pages were done in cypress. This PR migrates them to playwright. importantly, do take note that there's a shift to testing them on email based login - easier to setup (done alr in prev PR) + majority of our sites are on email based login. (also more complex)

Solution

1. Add a getApi method - we need this because we set baseURL to be that for our frontend (so that navigation works fine)
2. migrate from using cypress selectors to playwright locators.

I think edit page spec might get quite big + encompass a lot of different types/permutations of editing. Should we consider splitting into markdown editing and tiptap editing?

Also, I think we can separate out the collection + resource room editing into a separate spec that focuses more on testing aspects that are more specific to those types of editing.

i dont have blocking comments for this specific pr, but i do air similar concerns to zj + think we need to cover the edge cases for the two different editors

agreed for tiptap + markdown - right now, goal is not to add more test specs but rather, to get to parity. lmk if you're ok w/ just adding md specs here and tiptap specs further down the line

Yup I think we can add the tiptap ones later. I think we are still in the midst of stablising tiptap so it would be a bit troublesome to create them right now.
