Enhancement: Event/Trip group expense tracking with smart contract settlement

[GustavoSena]

Description

Create a special group type for events or trips where participants track shared expenses and settle up automatically via a smart contract.

Features

Event Creation

• Create an "Event" or "Trip" with participants
• Set event name, description, dates
• Invite contacts to join

Expense Tracking

• Each participant logs expenses they paid
• Attach receipts/notes to expenses
• Real-time running total per person

Smart Contract Settlement

• Calculate who owes whom
• Deploy settlement contract that:
  • Collects funds from debtors
  • Distributes to creditors
  • Only executes when all funds received
• Single transaction settlement for complex multi-party debts

Benefits

• Simplified group expense tracking
• Fair and transparent settlement
• Eliminates "who paid whom" confusion
• Trustless settlement via smart contract

Technical Considerations

• Settlement contract design (escrow pattern)
• Gas optimization for multi-party transfers
• Event state management in database
• Real-time sync for expense updates
