Fix development build

[adamgoth]

I encountered several errors trying to build the app on the development branch. This PR addresses those.

• Update webpack module rules to fix webpack build failures
• Fixes early terminated string in prompts.ts
• Fixes incorrect name of function imports from ./rag in ollama.ts
• Fixes type error when creating chain in askOllamaRAG function
• Updates parsing of json string response in frontend/utils/utils.ts
• Handles errors when parsing JSON

The development branch should now build without errors and correctly display a response from ollama.

I saw the Windows build failed again. It looks related to this line: https://github.com/MorpheusAIs/Lite-Client/pull/51/files

It appears the intention was to make loadingGif undefined, but instead a string value of 'undefined' was used, so it's looking for a gif by that name that doesn't exist. I pushed an update to remove the single quotes, which should hopefully fix the build.

Looks like a network issue of some kind in the latest run
