Version 3.8 sent to AppStore (color themes, reading wraps, a lot of fixes)

[petrjahoda]

■ New features
- Reading Wrap: a story-style recap of your reading, with covers, stats, and superlatives. Opens from Home, Stats, a monthly banner, or the yearly takeover, and any card can be shared.
- Personalize the whole app with a surface theme. Pick a color in Settings → Appearance and tune background and section-fill strength with sliders. Your choice syncs across your devices.
- A new custom color picker with Spectrum and Sliders tabs, used for both the app theme and reading color presets.
- Import books straight from Files. A new + button in the Library opens a multi-select picker for EPUB and PDF, with batch progress, cancel, and duplicate detection.
- New library-wide bookmark manager. See every bookmark from every book in one place, grouped By Book or By Date, with search and tap-to-open. Opens from the Home toolbar.
- Download PDFs from OPDS catalogs, not just EPUBs. Each imported book opens in the right reader automatically.
- Import fonts without leaving the reader. A new + in the EPUB fonts sheet adds fonts mid-book, and the list refreshes instantly.
- First launch now seeds a small starter library so there is something to read right away.

■ Improvements
- Every sheet now uses a standard navigation bar with the close button on the leading edge, matching iOS conventions. Reader sheets in landscape get a tighter header and the right width.
- Redesigned share cards for books, milestones, highlights, and Wrap: solid artwork with no transparent edges, and actions in the toolbar.
- Recap is more interactive: swipe through the cover fan, scrub periods with a horizontal date strip, and see every finished book on one cover wall.
- Highlight notes can be edited inline.
- Restyled full-screen image viewer, with smoother panning when zoomed.
- Calibre now detects better changes per book, so unchanged books are no longer re-imported.
- Clearer OPDS downloads: a green check and a success haptic confirm when a book finishes importing.
- Refreshed onboarding, library location sheet, Library import button, and audiobook toolbar.

■ Fixes
- Fixed a crash when opening a book whose description contains HTML.
- Fixed Files import reporting "0 imported" for readers who had never picked a library folder.
- Fixed OPDS catalogs (e.g. Kavita) showing the same book several times while hiding others.
- Fixed the image browser opening the wrong image on first open, and images sitting off-center.
- Fixed the Roadmap detail view going blank after a refresh.
- Fixed reader search fields on iPad needing two taps before the keyboard appeared.

■ Accessibility
- Broad VoiceOver and Dynamic Type pass across the reader, library, stats, and sheets: charts inside cards are reachable again, oversized text no longer breaks layouts, low-contrast text is readable in light mode, small controls got full-size tap targets, and the new color picker is fully operable with VoiceOver.

■ Localization
- All the newly added text is natively translated across all supported languages.
