Multi-debt payoff plan (avalanche vs snowball)

Given several debts and a fixed monthly budget, simulates the avalanche (highest interest rate first) and snowball (smallest balance first) strategies month by month — paying the minimum on every debt and rolling the extra (plus freed-up minimums) into the target — and returns the payoff order, months, and total interest for each, plus how much interest and time avalanche saves. If the budget can't overcome the interest, the debt is flagged as not paid off within a 50-year horizon. Deterministic; not financial advice.
