- Envelopes view: "Available to Budget" card shows checking+savings balance
minus total envelope allocations — turns red if over-allocated
- Income transactions in ManualEntry: envelope picker labeled clearly,
green highlight, helper text explaining effect on Available to Budget,
default option "Leave in Available to Budget"
- Fix account delete: now removes the account's transactions and
recalculates envelope spending
- Fix transaction edit/delete: use functional state updater to avoid
stale closure bug on accounts/envelopes recalculation
