- Migration 002: variable_amount boolean column on bills (default false)
- Bills form: 'Variable amount' checkbox; amount field becomes optional
'Typical amount' when checked; table shows 'varies (~$X)' and a 〜 badge
- Paycheck view: variable bills show a pencil edit button to enter the
month's actual amount, stored as amount_override on paycheck_bills
- New PATCH /api/paycheck-bills/:id/amount endpoint
- Lazy generation still works: setting an amount on a virtual paycheck
generates it first then saves the override
