fix: 8 AI services were not using configured provider

CRITICAL FIX: Auto-labels, notebook summaries, and other AI features
were not working because 8 services were calling getAIProvider() WITHOUT
passing the config parameter.

This caused them to use the default 'ollama' provider instead of
the configured OpenAI provider from the database.

ROOT CAUSE ANALYSIS:
Working features (titles):
- title-suggestions/route.ts: getAIProvider(config) ✓

Broken features (auto-labels, summaries):
- contextual-auto-tag.service.ts: getAIProvider() ✗ (2x)
- notebook-summary.service.ts: getAIProvider() ✗
- auto-label-creation.service.ts: getAIProvider() ✗
- notebook-suggestion.service.ts: getAIProvider() ✗
- batch-organization.service.ts: getAIProvider() ✗
- embedding.service.ts: getAIProvider() ✗ (2x)

FIXED: All 8 services now properly call:
  const config = await getSystemConfig()
  const provider = getAIProvider(config)

This ensures ALL AI features use the provider configured in the admin
interface (OpenAI) instead of defaulting to Ollama.
