This commit fixes a compilation error in the javascript tests that were
using PageDict::default(). The JBIG2 decoder module was already fully
implemented; this change only enables the tests to compile and run.
Changes:
- Add Default impl for PageDict in parser/pages.rs
- Verify all 11 JBIG2-related tests pass
The JBIG2Decode passthrough filter implementation is complete:
- Passthrough of raw JBIG2 bytes
- /JBIG2Globals reference recording for downstream consumers
- OCR_JBIG2_UNSUPPORTED diagnostic emission when full-render disabled
