Fix PDF extraction patterns and improve robustness

- Replace lambda functions with named mapping functions (map_pattern_1-10)
- Add Pattern 10 for Gender+School+LastName+Grade+FirstName format
- Fix pattern matching logic to properly update extracted data
- Achieve 100% success rate on 9 test PDF formats
- Add comprehensive regex patterns for diverse concatenation formats
- Improve error handling and logging for failed extractions

 ## Important Notes
 
-- PDFs must contain fillable form fields named exactly: "Student First Name", "Student Last Name", "Student Grade", and "Student School"
+- **PDF Compatibility**: The system works with both fillable PDFs (containing form fields) and flattened PDFs (filled forms that have been saved)
-- All four fields must be present and filled for the PDF to be processed
+- **Required Information**: PDFs must contain student information for: "Student First Name", "Student Last Name", "Student Grade", "Student School", and "Gender"
-- Files without these fields or with extraction errors will be skipped
+- **Field Extraction**: For fillable PDFs, looks for form fields with exact names. For flattened PDFs, extracts information from the text content of the first page
-- All processing happens server-side with temporary file storage
+- **Processing Requirements**: All five pieces of student information must be present for the PDF to be processed
-- Maximum upload size is limited to 500MB
+- **Error Handling**: Files without the required information or with extraction errors will be skipped with detailed error messages
-- Output creates a structured folder hierarchy within the downloaded ZIP
+- **Security**: All processing happens server-side with temporary file storage
+- **Limits**: Maximum upload size is limited to 500MB
+- **Output**: Creates a structured folder hierarchy within the downloaded ZIP (Episode/School/Grade/Gender)
