Client configuration persistence

Problem

Currently, the FTP-Wire client requires the user to manually configure the following parameters every time the application is launched:

• Username
• Host
• Port

This repetitive setup negatively impacts usability and user experience, especially for users who frequently connect to the same remote server.

Proposed Solution

Introduce support for persisting client configuration using a configuration file (e.g. .conf or .ini). The client should:

• Load saved configuration values automatically on startup
• Allow users to override or update these values when needed
• Save updated configuration back to disk for future runs

Expected Behavior

1. values are stored in a configuration file (e.g. client.conf or client.ini)
2. On subsequent runs:
   • The client automatically loads the saved configuration
   • The user may accept the defaults or provide new values
3. If the configuration is updated:
   • The file is rewritten with the new values
