Force https for jetpack sites

[adborbas]

Closes WOOMOB-1529

Description

Force https scheme for siteAddress.

The fix ensures that when creating a JetpackSite from a Site, the URL always uses the https scheme. This logic lives in a small private extension (jetpackCanonicalURL), which felt like the right place since it’s well-contained and only runs once (or at most a few times).

I considered a more elaborate approach using a request retrier that would detect ATS failures, retry with https, and persist that preference on the Site for future requests. However, that felt overly complex for such rare cases, so I opted for this simpler and more predictable solution.

Steps to reproduce

This one is a bit tricky as it requires fiddling with the site settings in NetworkAdmin, so instead I'd suggest mocking a network response in ProxyMan.

1. Start on trunk branch. Build and launch the app locally while connected to Proxyman or any other network monitoring tool.
2. Look for the https://public-api.wordpress.com/rest/v1.1/me/sites?... request. Which should contain a response object

   {
     "sites": [
       {
         "ID": 000000000,
         "name": "Buy cheap stuff expensive",
         "description": "",
         "URL": "https://<your-site>.com",

3. Set up a local map for that request and mock the URL property to use httpinstead of https. So turn

   "URL": "https://<your-site>.com" ->  "URL": "http://<your-site>.com"
   

4. Force close the app.
5. Start the app.
6. Note that bookings do not load. This verifies that trunk is broken.
7. Check out this branch.

   git checkout adborbas/woomob-1529

8. Start the app.
9. Note bookings load without an issue.

Hey @adborbas, Thx for the fix.
I'm not sure how to follow these testing steps:

• Start the app without mokcing and look for the https://public-api.wordpress.com/rest/v1.1/me/sites request.
• Set up a local map for that URL and mock the /sites/<the_site_you_load_if_multiple>/URL propery for use the http version of the site URL.

Could you please describe what to do there in detail?

[adborbas]

@RafaelKayumov I've updated the steps. Could you please see them again? Please let me know if they need more adjustments.

On my side I had to open sites selected to trigger the sites request that delivers the URL parameter.

LGTM. Works as described.
