[FEATURE]: Education AI Suite - Pipeline configuration panel with dropdowns to configure pipeline for Smart Classroom sample app

Description Implement dropdown menus in the Pipeline Configuration Panel to allow users to select from a list of pre-validated models for each stage of the pipeline: ASR, LLM, VLM, detection, and classification.

Assumptions

• Model options are defined in a config file or JSON schema
• Selection updates the backend pipeline configuration
• No dynamic model loading required for MVP

Dependencies

• Model registry or config file
• Backend pipeline controller
• GUI dropdown components

Expected Output

• Dropdowns for:
• ASR (e.g., Whisper, Conformer)
• LLM (e.g., Qwen2-7B, LLaMA-3)
• VLM (e.g., Qwenvl2-2B)
• Detection (e.g., YOLOv8)
• Classification (e.g., ResNet18)

Acceptance Criteria

• Dropdowns are populated on GUI load
• Selection updates the pipeline config
• Invalid combinations are prevented
