MODEL_FILTER_ENABLED -> ENABLE_MODEL_FILTER

Current config assumes /data/docs to be part of the current data directory.

This allows DOCS_DIR to be mounted from a different path outside of DATA_DIR, or falls back to the previous behaviour if DOCS_DIR is not in the environment

With default of `False`.

* Introduce WHISPER_MODEL_AUTO_UPDATE env var
* Pass local_files_only to WhisperModel()
* Handle cases where auto-update is disabled but model is non-existent

* Add config variable RAG_EMBEDDING_MODEL_AUTO_UPDATE to control update behavior
* Add RAG utils embedding_model_get_path() function to output the filesystem path in addition to update of the model using huggingface_hub
* Update and utilize existing RAG functions in main: get_embedding_model() & update_embedding_model()
* Add GUI setting to execute manual update process
