several improvements and fixes

[DickHorner]

This pull request introduces several improvements and fixes across the project, focusing on environment setup, model loading, drag-and-drop UI behavior, and file handling logic. The key updates ensure smoother user experience, more robust model management, and correct file path handling.

Environment and Dependency Setup:

• Updated Start.bat to ensure the correct activation of the visomaster Conda environment, explicitly calling the Conda batch script and setting an environment variable to prevent library conflicts.

Model Loading Improvements:

• Re-enabled automatic model file downloading in models_processor.py if the required model file does not exist, improving robustness for new or missing models.

UI Drag-and-Drop Enhancements:

• Modified main_ui.py to allow drag-and-drop actions directly on the viewport() of targetVideosList and inputFacesList, fixing issues where drops on the list area were previously ignored.

File Handling and Worker Logic Fixes:

• Refactored ui_workers.py to correctly handle file paths when loading videos and images from a folder, ensuring that the full path is used and avoiding double-joining of paths. [1] [2]

Resource File Update:

• Updated binary data in media_rc.py, reflecting changes to embedded a variety of resources.

Pull request overview

This PR refines environment setup, model loading, drag‑and‑drop behavior, and path handling to improve robustness and usability of the VisoMaster application.

Changes:

• Adjusts Start.bat to explicitly activate the visomaster Conda environment and set KMP_DUPLICATE_LIB_OK.
• Re-enables automatic model downloading in models_processor.load_model when a model file is missing.
• Fixes media path handling in TargetMediaLoaderWorker / InputFacesLoaderWorker and enables drag‑and‑drop directly on list viewports; updates embedded resources via media_rc.py.

File	Description
Start.bat	Changes environment activation to a hardcoded Miniconda conda.bat path and sets KMP_DUPLICATE_LIB_OK before launching the app.
app/processors/models_processor.py	Re-enables on-demand model file download if a model path does not exist before instantiating an ONNX runtime session.
app/ui/widgets/ui_workers.py	Simplifies media path handling by iterating directly over absolute paths from helper functions and removing redundant os.path.join for faces.
app/ui/main_ui.py	Enables viewport().setAcceptDrops(True) on target and input face list widgets to ensure drops on the list area are handled properly.
app/ui/core/media_rc.py	Updates compiled Qt resource binary data to reflect changes in embedded assets.

Hardcoding the Conda activation script path to %USERPROFILE%\miniconda3\condabin\conda.bat makes this launcher brittle for users who installed Miniconda/Conda in a non-default location or are using Anaconda, which will cause environment activation (and thus app startup) to fail. Consider resolving conda.bat via %PATH%, using %CONDA_PREFIX%/%CONDA_EXE%, or adding a small detection/fallback mechanism so the script works across different Conda installations.
