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)
