Leo query set to current URL, can't be changed

[wknapik]

Description

The only Leo query possible seems to be the current URL. Querying Leo leads to a blank screen.

Steps to reproduce

1. Type a query - Leo is not suggested
2. Hit enter to ask Brave Search instead
3. Click on the address bar, the current url is shown and the query suggested for Leo is that url
   
4. Hit backspace to replace the url with a query, but the suggestion remains, even after typing a new query

Actual result

Leo should be queried for whatever the user typed and that should actually work

Expected result

Leo can only be queried about the current URL

I'm also seeing #36145, so the blank page part of this issue might be this.

I didn't find a duplicate issue for the fixed query.

Enabling Settings -> Brave Shields & privacy -> Show autocomplete in address bar causes the Leo suggestions/queries to no longer be fixed to the current URL

[SergeyZhukovsky]

So the issue basically due to global autocomplete settings is disabled Settings -> Brave Shields & privacy -> Show autocomplete in address bar. We should either hide Setting->Leo->Show autocomplete in address bar when the global autocomplete setting is off or perhaps better imo and what @wknapik suggested is to show it as off in Leo section and once a user tries to enable it, give a warning that this move is going to enable global autocomplete setting as well.

[mattmcalister]

On desktop the Leo settings have a button for Adjust autocomplete suggestions which takes you to the global settings. And then the global settings provide options for enabling/disabling autocomplete data types. That solution works well, imo. We would need a new submenu page for the Show autocomplete in address bar setting in Brave Shields & privacy, and then we could add new data types later if we wanted to, such as bookmarks and history.
