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. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
