[stable27] fix: checkbox now allows shift-click and multi-select

[emoral435]

• Resolves [Bug]: Allow multi-select for files in trash #42364

Summary

PROBLEM: Shift clicking the files in the files app of stabl27 does not allow the functionality to select multiple files at once

• Originally, I thought that this was regression within the Vue #app-content components, but after testing, I found that it was due to the logic behind our legacy PHP templates and the JS that was bundled with it
• To fix this, shift the event to the general select class. That means that the onChange behavior is not needed - we can now use onClick and prevent the default action that causes double clicking, as we do the clicking functionality ourselves
• The check used to see if we are choosing a range did not fall in line with the other shift-select logic, so I made them now similar

files.cy.ts is failing

@skjnldsv Cypress failures seem unrelated: re-ran tests again and they passed 🎉 (failed test is the blocker). Proof:

Still needs to be rebased, but should be ready to be merged 🎉 Question though, I tried running npm run cypress:e2e but it gets stuck here ->

Any ideas why? This is related to another PR I want to get merged in for stable28

Cypress tests seems to be flaky since 2 days in various PRs 😩

[skjnldsv]

Yeah, we notived some missing cypress fixes for 27.
Master is getting some other fixes too
