### Problem Description

Currently, `Village` and `City` are used interchangeably. This leads to confusion amongst users.

For example:

- When creating a customer users have to provide a `City`
- On an initial instance of MPM no cities are available
- Users have to use the `Create Village` button to add a `City`

Which is unintuitive.

### Proposed Solution

Please consolidate all users of `city` and `village` to **only use `Village`**.

This covers

- Function calls
- `cities` tables
- UI elements

### Alternatives Considered
