Environment Variable Updates

In this PR, I've made the following changes:

Removed:

• Environment variables that were documented but not accessed:

ENABLE_LITELLM
LITELLM_PROXY_HOST
LITELLM_PROXY_PORT
PORT
RAG_WEB_SEARCH_DOMAIN_FILTER_LIST
http_proxy
https_proxy
no_proxy

• Deprecated environment variables:

OLLAMA_API_BASE_URL
SEARCH_QUERY_PROMPT_LENGTH_THRESHOLD

• Removed the LiteLLM section to avoid confusion.

Added:

• New environment variables:

USER_PERMISSIONS_CHAT_EDITING
USER_PERMISSIONS_CHAT_TEMPORARY
ENABLE_ADMIN_CHAT_ACCESS
ENABLE_MESSAGE_RATING
DEFAULT_LOCALE
FUNCTIONS_DIR
FONTS_DIR
CORS_ALLOW_ORIGIN
CONTENT_EXTRACTION_ENGINE
TIKA_SERVER_URL
RAG_FILE_MAX_COUNT
RAG_FILE_MAX_SIZE
ENABLE_SEARCH_QUERY
SEARCHAPI_API_KEY
SEARCHAPI_ENGINE
AUDIO_TTS_API_KEY
AUDIO_TTS_SPLIT_ON
AUTOMATIC1111_API_AUTH
COMFYUI_WORKFLOW
TOOLS_DIR

Other Improvements:

• Updated prompt templates
• Rearranged environment variables in the documentation for better organization
• Added missing environment variables that were previously undocumented

Special thanks to @cheahjs for contributing new environment variables and creating a script to scan for missing env vars in the documentation (PR #207).

I didn't realize I did duplicate work until after having submitted my own PR. My sincere apologies @cheahjs. To compensate for the mistake, I've taken the initiative to merge the missing pieces from @cheahjs' PR into mine, in the spirit of collaboration and efficiency. I hope this is okay with you, @cheahjs, and I appreciate your understanding.

The "Proxy Settings" section should be kept around - the _proxy env vars aren't directly used by Open WebUI, but things like AIOHTTP will respect them. They were added in response to discussion threads around making Open WebUI use proxies.

[cheahjs]

Same with PORT, it's not used in the Python codebase, but is used by the backend startup script to configure uvicorn: https://github.com/open-webui/open-webui/blob/main/backend/start.sh#L8.

These were added to the ignore list in my script because they were used outside of Open WebUI's Python configuration code.

Understood! Will fix these hiccups now. 👍🏼

Edit: Fixed (Reverted removal of these environment variables you've mentioned)!
