Bug 41709: Fix EDIfact special character escaping in GIR segments and other fields

Apply encode_text function to all text fields in EDIfact Order messages
to properly escape special characters (?, ', :, +) that could break
message parsing. Previously only bibliographic description fields were
escaped, but GIR segments containing collection codes, branch codes,
item types, call numbers, and other data were vulnerable.

Test plan:
- Verify all existing tests pass
- Added comprehensive tests for special character escaping in GIR segments
- Confirmed that fields containing ?, ', :, + are properly escaped
