reboot: replace vision pipeline with Excel-first manual journal

Pipeline-ul vision (screenshot extraction + CSV append + Python stats) era
greoi pentru backtest semi-manual. Înlocuit cu un singur template Excel
generat din openpyxl + Dashboard cu comparație 5 strategii management pe
aceleași semnale blackbox.

- Strategii: TP0 only / TP1 only / TP2 only / Hybrid+BE / Hybrid no BE
- Input minim (12 coloane galbene); Sesiune și Zi derivate auto din Data+Ora
- Dashboard cu coloana "Cum citesc" + secțiune Glosar cu exemple concrete
- Breakdowns PER SESIUNE / STRATEGIE / INDICATOR / DIRECȚIE
- Equity curve cu 5 linii

Eliminat: m2d-extractor agent, /backtest, /batch, /m2d-log, /stats slash
commands, scripts/{append_row,pl_calc,stats,manual_log,regenerate_md,
vision_schema,calendar_parse}.py, tests/, screenshots/, data/extractions/.
