fix: resolve issue where extension would not load on sites

[ItsANameToo]

Summary

Odd issue, but the extension stopped working on sites like https://demo.arkconnect.io/ and https://live.arkscan.io/ with the release of chrome v130, throwing in error in devtools regarding Content Security Policy and it not wanting to load the content.js file. After a lot of configuration adjustments it seems to work with this small change where the content_scripts gets changed from purely https to both https and http.

Note that it only works when both are included. Having either https or http in itself will not allow the extension to work, but when the array contains both is magically works. The Firefox manifest remains as-is as it works fine there with just the https content scripts entry.

Checklist

• I checked my UI changes against the design and there are no notable differences, including responsiveness
• I checked my (code) changes for obvious issues, debug statements and commented code
• I opened a corresponding card on Clickup for any remaining TODOs in my code
• I added a short description on how to test this PR (if necessary)
