General improvements (#151)
* Updated folder synchronization logic and redesigned the file type filter dialog. * Fixed CFI generation and navigation stability in the EPUB reader. * Improved CFI scrolling and position calculation in the EPUB reader by implementing text node traversal using `TreeWalker`. This ensures accurate positioning and scrolling when a CFI offset spans multiple fragmented text nodes. * fix fb2 multiline titles, retain footnotes, and prevent stream leaks - Fix FB2 titles with multiple paragraphs by inserting breaks/spaces - Prevent resource leaks by properly closing InputStreams in all importers - Retain "notes" and "comments" sections in FB2 instead of skipping them - Add support for FB2 poem, stanza, cite, and link tags * Implement persistence for zoom and pan states when pan lock is enabled in the PDF reader. * Added `FileTypeBadge` to home and library screens * Bump version to 1.0.41(42)
