fix(pdf_extract_kit): specify utf-8 encoding when reading model configEnsure the model configuration file is read with utf-8 encoding to support
non-ASCII characters and prevent potential encoding errors.

Specify utf-8 encoding when opening the configuration file to ensure
compatibility with files containing non-ASCII characters, avoiding potentialencoding errors.

fix(magic-pdf): add default values and improve warning logs for config optionsEnsure that 'temp-output-dir', 'models-dir', and 'device-mode' have sensible default
values in case they are not specified in the config file.

Improve the model loading mechanism in magic_pdf by implementing a Singleton
pattern to reduce redundant model instantiation. Additionally, enhance the
command-line interface to support input from list files, allowing batch
processing of multiple PDF documents.

Introduce a Singleton pattern to manage custom models in the magic_pdf module.
This change improves the efficiency by ensuring that a single instance of the
custom model is created and reused, thereby reducing the overhead of multiple
instantiate calls for the same model configuration.
