[Bug]: Consolidate installation to a single requirements.txt and remove manual dependency installs

[titanh]

Bug Description

Description:
Currently, the installation instructions require users to perform multiple manual commands:

python -m pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
python -m pip install "paddleocr[all]"
pip install -r requirements.txt

This setup leads to potential issues:

Manual steps make versioning and reproducibility harder to enforce.

Some dependencies are installed outside requirements.txt, so tracking / pinning becomes fragmented.

New users may be confused by multiple commands and CUDA-specific indexing (e.g., cu118) hard-coded.

CI / automated deployment (Docker, pipelines) benefit from a single consistent install command.

1. Move all dependencies, including paddlepaddle-gpu, paddleocr[all], and supporting libraries into the requirements.txt. For example:

requirements.txt

paddlepaddle-gpu==3.0.0 -f https://www.paddlepaddle.org.cn/packages/stable/cu118/
paddleocr[all]

Steps to Reproduce

python -m pip install -r requirements.txt
