feat(#127): refactor LlmService to use provider pattern
Refactor LlmService to delegate to LlmManagerService instead of using Ollama directly. This enables multiple provider support and user-specific provider configuration. Changes: - Remove direct Ollama client from LlmService - Delegate all LLM operations to provider via LlmManagerService - Update health status to use provider-agnostic interface - Add PrismaModule to LlmModule for manager service - Maintain backward compatibility with existing API - Achieve 89.74% test coverage Fixes #127 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
