feat(app): implement character login and destination setting for multiple characters

This commit introduces several key features:

- **Multiple Character Support**: The application can now handle multiple logged-in EVE Online characters.
- **List Characters**: A new function `ListCharacters` allows retrieving a list of all authenticated characters.
- **Set Destination for All**: The `SetDestinationForAll` function enables setting a destination for all logged-in characters simultaneously.
- **UI Updates**: The frontend has been updated to display logged-in characters and to allow setting destinations for all characters.
- **Backend Refinements**: The ESI SSO logic has been improved to support refreshing tokens for multiple characters and to handle the new multi-character functionality.
- **Dependency Updates**: Dependencies have been updated to their latest versions.
