feat(extraordinary-expenses): Add module for extraordinary expenses

Introduces a new module to manage and track extraordinary expenses within condominiums. This includes defining expense items, sharing arrangements, and attaching relevant documents.

The module adds new types for `ExpenseItem`, `ExpenseShare`, and `ExtraordinaryExpense`. Mock database functions are updated to support fetching, creating, and managing these expenses. UI components in `Layout.tsx` and `Settings.tsx` are modified to include navigation and feature toggling for extraordinary expenses. Additionally, new routes are added in `App.tsx` for both administrative and user-facing views of these expenses.
