[v1.69.0] Hide read rework

Hide read is probably one of the most important features of the app. This update reworks the feature so it works better.

Changes so far

• Change hide read to a combo button: a button on the left side that works like the old hide read effect and a switch on the right side.
• Add new FAB long press action to toggle hide read.
• Fix a bug where if you launch the app with no internet then the app will continue to show a no internet error even if internet is re-established later.
• Fix a bug when editing a comment where the old comment is shown instead of the new comment
• Fix a bug where the wrong image is shown in the post list.
• Fix a bug where the custom font is not applied to post titles if Prefer title text is on.
• Fix a bug where the custom font is not applied to community names/usernames.
• Fix a bug where the navigation rail would show when it shouldn't
