fix(canvas): use explicit empty-string check in BudgetSection to preserve zero-credit budget

Browse Source 
parseInt("0", 10) || null evaluates to null, silently converting a
zero-credit budget to unlimited. Switch to raw !== "" ? parseInt() : null
so budget_limit: 0 is sent correctly. Adds regression test.
