fix(pdftract-34hxw): correct PDFDocEncoding test expectations
Fixed test_decode_pdf_string_pdfdocencoding_latin1 to expect uppercase
"ÉÈÀ" instead of lowercase "éèà" for bytes [0xE9, 0xE8, 0xE0], matching
PDF 1.7 spec Annex D.2 PDFDocEncoding table.
The implementation (value_text.rs) already correctly implements:
- TextValue struct with value, default, multiline, max_length fields
- decode_pdf_string for PDFDocEncoding/UTF-16BE BOM decoding
- extract_text_value for extracting /V, /DV, /Ff, /MaxLen entries
- FormFieldValue::Text integration via acro_field_to_value
All acceptance criteria PASS:
- Text field with /V → FormFieldValue::Text { value: Some(...), ... }
- UTF-16BE BOM-prefixed /V → correct Unicode decode
- /Ff multiline bit set → multiline: true
- /MaxLen → max_length: Some(N)
- Empty /V → value: Some("")
- Missing /V → value: None
