fix(clinical): red flags, one crisis rule, callback after a crisis, one table of numbers

Clinical review of the questionnaires (ADR-013):
- Red-flag block first in stage 1 (config/instruments/red_flags.yaml); any «Да» stops the
  questionnaire with an acute alert and the help screen of its category.
- One crisis rule: the crisis screen opens at a HIGH C-SSRS risk only; moderate stops and goes
  to a psychiatrist (24 h as a guide), low is a flag with the safety plan. PHQ-9 item 9 with a
  negative screener is a discrepancy flag; without a completed screener it asks the C-SSRS at once.
  config/questionnaire.yaml: cssrs_positive_policy graded (C01).
- Every crisis leaves a callback task for the doctor on duty (post_crisis_call, one per patient)
  and the app asks how the person is the next day, the safety plan one tap away.
- Routing: risk and flags first, scales second; PCL-5 >= 50 no longer means a priority
  appointment (pcl5_severe is moderate on the dashboard too).
- Crisis numbers live only in config/texts/crisis.yaml; texts and the agent prompt refer to them
  via {phone:<key>}. Fixes the children's helpline offered to adults by the chat agent.
