- Add threshold_type field (fixed/percentage) to system and user settings - Add total_recharged field to users table, auto-incremented on balance credit - Percentage mode: effective threshold = total_recharged × percentage / 100 - User-level threshold_type inherits from system default when not set - Update admin settings UI with radio selector (fixed amount / percentage) - Migration: 102_add_balance_notify_threshold_type.sql
