fix: Memory Status card respects configured embedding provider (#336) (#373)

The Graph Memory Status card now correctly validates the configured
embedding provider (GRAPHITI_EMBEDDER_PROVIDER) instead of always
requiring OPENAI_API_KEY.

Supported providers:
- openai (default, requires OPENAI_API_KEY)
- ollama (local, no API key needed)
- google (requires GOOGLE_API_KEY)
- voyage (requires VOYAGE_API_KEY)
- azure_openai (requires AZURE_OPENAI_API_KEY)

Changes:
- Add validateEmbeddingConfiguration() in utils.ts
- Update memory-status-handlers.ts to use new validation
- Display provider-specific error messages when keys are missing

Fixes #336
