fix: persist token counts from gateway to SessionEntry and SQLite (#316)

The gateway's _run_agent returns input_tokens/output_tokens in its
result dict, but these were never stored to SessionEntry or the SQLite
session DB. Every session showed zero token counts.

Changes:
- gateway/session.py: Extend update_session() to accept and persist
  input_tokens, output_tokens, total_tokens, estimated_cost_usd
- gateway/run.py: Pass agent result token totals to update_session()
  and call set_token_counts(absolute=True) on _session_db after
  every conversation turn
- tests/test_token_tracking_persistence.py: Regression tests for
  SessionEntry serialization and agent result token extraction

Closes #316
