fix(mining): remove duplicate burn mechanism from mining-service

Mining-service incorrectly implemented its own burn mechanism (10-year cycle) which was not in the requirements. Per requirements, only trading-service should handle per-minute burn (4756.47/minute). Removed: - BlackHoleRepository and all burn-related methods - executeBurn() from mining distribution service - Burn stats from admin API and queries - Burn progress UI from mining admin web Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
