Implement a QFieldCloud server combobox to ease multi-server environments

[nirvn]

Looks:

This added combobox functionality makes it much easier to switch back and forth from the default QFieldCloud server (https://apps.qfield.cloud) and custom server(s). No need to remember the exact URL, just pick it from the history of URLs 🥳

This also aligns QField to QFieldSync where we've had a combobox for a long time:

Two questions:

• how does one delete a URL
• how does one get an ordered list of URLs

Nice change anyway, but without the ability to prune the list I think it is dangerous.

@suricactus , the list of URLs == a saved list of URLs successfully connected to; by default there's only the defaultUrl() in there.

On the security front, ATM the last connected URL always shows, so we're adding exposure to a URL string (not credentials) if the person connects to a 3rd party URL then goes back to the app.qfield.cloud server. Otherwise things essentially stay the same.

Hey, sorry, I meant the order of the list. If I read the code correctly, it only appends in the end. Would be better if we sort alphabetically OR we have the most recent on top.

It is more that I work for OPENGIS.ch GmbH and I was connecting to cloud.opengis.ch. Then I leave the company and join QFieldCloud GmbH and I need to connect to cloud.qfield.cloud for my daily work. I don't want to see cloud.opengis.ch anymore.

@suricactus , ah -- I kind of like having the default URL as the first choice, but we can order alphabetically too.

@suricactus , with regards to deleting URLs, ATM it's not possible (other than by wiping the user profile storage). Would you be OK to merge this as is and address these issues in follow up PRs?

Sure, if the follow-up is planned soonish, go ahead!
