M5 already broadcast through the shared _scan_timeframe path but was documented as data-only (docstring, CLAUDE.md, DOCUMENTATION.md, plus a phantom `if tf == M5: return` step that never existed in code). Align all docs/comments so M5 alerting at C+ grade is the intended, documented behavior. Remove the live dashboard entirely per request: the 30s refresh loop, per-scan refresh, boot send, and the dashboard-only stats layer (_signal_stats / _stats_updated / _update_signal_stats and its call sites, _format_stats_dashboard and its helper constants). Drop now-unused ZoneInfo import and dashboard mentions from help/autoscan/boot messages and the test suite. The WebSocket level-breach monitor and level cache are untouched. Tests: 136 passed, 0 failed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
