[Reader] Next Chapter skips 0.1 when a 0.01 chapter exists (decimal ordering issue)

[Leizurly]

Description:
When a manga uses decimal chapter numbers (0.1, 0.2, 0.3, etc) and a chapter numbered 0.01 is uploaded (intended to appear before 0.1), the chapter list displays in the correct order in the UI. However, using Next Chapter navigation from 0.01 skips 0.1 and jumps directly to 0.2.
Expected behavior: advancing from 0.01 should go to 0.1.

Steps to Reproduce:

1. Create or use a title with chapters numbered: 0.1, 0.2, 0.3 (and so on).
2. Upload a chapter numbered 0.01 so it appears before 0.1 in the chapter list.
3. Open the reader on chapter 0.01.
4. Use Next Chapter (keyboard shortcut, or sidebar button).
5. Observe it goes to 0.2 instead of 0.1.

Additional Information:

• The chapter list order appears correct (0.01 shown before 0.1).
• The issue seems limited to “next chapter” resolution/ordering logic, likely treating 0.01 and 0.1 in a way that breaks adjacency (possibly numeric parsing or rounding/normalization).
• I deleted the 0.01 chapter on my specific series as a workaround, but this should be reproducible site-wide for any title that uses 0.xx chapter numbers.
• I checked the current “Known bugs” list and did not see this exact “next chapter skips 0.1 when 0.01 exists” behavior listed.

Additional Context:

MangaDex allows uploading 0.xx chapters, so it would be ideal if navigation respects the same ordering the UI shows. This could silently confuse readers if uploaders do not notice the skip. Thanks!
