feat: Add real job submission for HuggingFace Jobs and Modal

Major Features:
- Implemented actual job submission using HuggingFace Jobs API (run_job)
- Added Modal job submission module for serverless GPU compute
- Extended Settings screen with comprehensive API key management

Settings Screen Enhancements:
- Added Modal API credentials (Token ID + Secret)
- Added LLM provider API keys field (ENV format) for all major providers
- Fixed security issue: Don't expose existing environment variables in UI
- Added validation and test connection for all API keys

HuggingFace Jobs Integration:
- Uses official run_job() API from huggingface_hub
- Auto-selects appropriate Docker image (python:3.12 for CPU, pytorch with CUDA for GPU)
- Auto-selects hardware flavor based on model size (cpu-basic, t4-small, a10g-large, a100-large)
- Passes all LLM provider API keys as secrets
- Configurable timeout (default: 1h)
- Returns actual HF job ID for tracking

Modal Integration:
- Configures Modal apps with appropriate GPU (T4, A10G, A100, H100, H200, B200)
- Auto-selects GPU based on model size
- Passes API keys via Modal secrets
- Ready for async execution

New Evaluation Form:
- Added timeout configuration field
- Now actually submits jobs instead of just showing configuration
- Displays detailed success/error messages with job IDs
- Shows platform-specific instructions

Security:
- API keys stored in session only (not persisted)
- Sensitive fields use password type
- Environment variables not exposed in UI
