data_provider: - Remove _generate_synthetic_data entirely — no more fake prices - Raise DataUnavailableError instead of falling back to synthetic data (no API key, daily limit hit, API returns no values, fetch failure) - Move rate limiter to module-level globals (_rate_lock, _rate_request_times, _rate_daily_credits) so all ForexDataProvider instances running in parallel threads share the same 8-credit/min and 800-credit/day accounting - _throttle now raises DataUnavailableError on daily limit (was silent return False) - Remove _no_api_data tracking, numpy/hashlib imports telegram_bot: - Detect F-grade reports caused by data unavailability and show clean "Data unavailable" line per TF instead of a garbled zero-price card Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
