Adds a Goals page where users can plan financial goals before committing
to them. Each goal shows:
- Required monthly contribution to hit the deadline
- Months remaining vs months at current savings rate
- Disposable income impact (what's left after the contribution)
- Feasibility banner (green if on track, red with month delta if not)
- Progress bar once savings are tracked
Goal types: one-off purchase, deposit/down-payment, emergency fund,
recurring investment — each with a description hint in the creation modal.
Data: Goal model + store CRUD in finance_goals collection.
Nav: Goals tab added between Portfolio and Sharing.
