Hospital: cut revival to 5k/level + add CHA haggle roll

Drops the after-insurance revival cost from level × 50k to level × 5k
(before-insurance still 5×). On check-in, Nurse Joy now lets the player
attempt a CHA save vs DC 15:
  - nat 1  → auto-fail, full price
  - <  15  → fail, full price
  - >= 15  → pass, bill halved
  - nat 20 → bill fully waived (no debit, no community-pot cut)
Outcome is pinned on the pending interaction (Discounted/Waived) so the
TOCTOU recompute at confirm preserves the discount/waiver and can't be
re-rolled. Bill DM reordered: itemized → after-insurance (pre-haggle) →
🎲 roll line + Nurse Joy reaction → final amount with strikethrough on
the pre-haggle figure.
