feat(org): rank the register by WSJF from Fibonacci estimates

kvb-org-wsjf: the chair asks its subordinates for Fibonacci estimates of business value and complexity, rasci.py estimate records them per party, and WSJF = median value / median complexity ranks the tasks. rasci.py wsjf prints the WSJF table with OKR and the task id; the register's show takes its Prio from that rank (an operator --prio pin first) and adds a WSJF column. Four descriptions were tightened to keep the listing budget.
