ai: implement ollama rewrite provider + ryan-salazar byline default

The press-release rewriter (ai_rewrite_jobs) was stuck because:
- BB_REWRITE_PROVIDER defaulted to "anthropic" in code, AND
- production env still had BB_REWRITE_PROVIDER=anthropic, AND
- ollamaProvider.rewrite() was a stub that threw "not implemented".
Every job since 2026-01-26 hit Anthropic 400 "credit balance too
low" — 12 failed_api in a row.

Changes:
- Implement ollamaProvider against /v1/chat/completions on the local
  Ollama (works against AI_001:11434 / llama3.1:70b). Same JSON
  contract as the Anthropic provider; gets prompt_tokens /
  completion_tokens out of Ollama's usage block.
- Flip the default provider from "anthropic" → "ollama" in
  getProvider(), so the rewriter works out of the box now that the
  Ollama implementation exists.
- Make the BB auto-story byline configurable via env. Default flips
  from a 12-name pen rotation to a single "Ryan Salazar" byline for
  Broadcast Beat (per editorial directive). AV Beat keeps its own
  pen pool. Set BB_AUTOSTORY_BYLINE=rotate to restore the old
  behaviour.

Production env still needs (set in Coolify dashboard):
  OLLAMA_ENDPOINT=http://10.10.0.66:11434
  OLLAMA_MODEL_DEFAULT=llama3.1:70b
  BB_REWRITE_PROVIDER=ollama
  BB_REWRITE_MODEL=llama3.1:70b
  (remove ANTHROPIC_API_KEY)
