Revert Prompt and Update ARASAAC Pictogram Fetching Logic
Description
We need to revert the prompt used in the cboard-ai-engine back to version 1.4.0 to improve pictogram fetching accuracy from ARASAAC. This task will involve several updates to the fetching and fallback mechanisms for ARASAAC pictograms.

Requirements

Revert Prompt: Update the prompt to match version 1.4.0 of cboard-ai-engine.

Use the 1.4.0 prompt to fetch pictograms from ARASAAC. The resulting data should create a new board.
Note: store all associated labels to show to the user.

404 Error Handling:

For any pictograms that return a 404 error in ARASAAC, implement a fallback to a new prompt (similar to the 1.6.0 version) provided by @hectoritr .
Use the ARASAAC "search" endpoint to retry fetching these pictograms.

For any pictograms that continue to return 404 after both attempts, we will rely on the user to either conduct their own search inside "Edit" or use GenAI as an alternative.

• Revert prompt to the 1.4.0 version.
• Pictograms are fetched and stored as per the primary prompt.
• All pictograms that encounter 404 errors are retried with a new fallback prompt.
• The user is given an option to manually search or use GenAI if the pictogram still returns a 404.

@AliLee0923 let me know when you need the new prompt.

Current prompt works well so far. I've just added a point for verb management.
If you think the engine doesn't work well, we might need to think about prompt again.

OK amazing!
