Build 393: AO3 styling, banners at the top, and PDF fixes

[briarrrn]

Build 393 is on TestFlight.

Please test

• AO3 styling in Fanfic Updates. Fics now keep their AO3 styling, such as tweet threads and text messages, when Fanfic Updates brings them in. For fics you downloaded earlier, open Fanfic Updates > AO3 Styling: it checks your fics, then you update each one, and your place, highlights and bookmarks come along. Tell me if a fic still looks different from the same work on AO3.
• Banners at the top. Messages from Apogee now drop in as one banner at the top of the screen, coloured by what happened. "Couldn't refresh" is one of them, with Retry.
• CarPlay. Jump Ahead is now a button beside speed, bookmark and chapters. After you jump, it should disappear. If it stays, or if Continue, Recent or Browse comes up empty in the car, tell me here.
• French or German? Open the card on a highlight and tell me if anything on it is still in English.

Also in this build

• Updating a fic has a clearer page: the fic and its new chapters at the top, Update at the bottom, and one bar that shows each step while it runs.
• Read opens the format your server ranks first, instead of asking which one every time.
• PDFs: select text and the highlight card opens, as it does in ebooks. Highlights sit on the words you chose, and pages should fill the screen's width.
• Opening a book's ebook after its audiobook now matches "Chapter One" to "Chapter 1", and says why when it can't move you to the chapter you were listening to.
• Speak lists your BookOrbit server's voices by their names, not their ids. Thanks to @Ribero.
• Browse: long-pressing a series offers Download All only for the books you don't have yet.
• Comics: the Group menu no longer disappears after "No story arcs for this series." An issue in two story arcs should appear under both.
• The A–Z rail in the Library gives a light tap you can feel as you move from letter to letter.
• When your BookOrbit server supports them: request a book's missing format from its page, request an ebook and its audiobook together, see when a downloaded book's file changed on the server, and get fresh results from Search in Match Metadata.

Prefer regular updates? Get Apogee on the App Store for updates without a beta expiry date. Install it without deleting Apogee first. You can stay on TestFlight to keep helping me test.

This build includes everything since build 391.
