- Refactored to parse page numbers as nibbles ((T<<4)|U) instead of decimal, preventing collisions between hex and decimal pages.
- Updated to format page IDs as Hex.
- Updated to display page IDs as Hex in the list.
- Ensures filler/housekeeping pages are correctly isolated.
Correctly map C12 and C13 control bits to fix misidentification of Swedish/Finnish (010) and German (001).
Also ensures Page model, Renderer, and UI properly propagate and display the detected language.
