Extract shared models, services, and application logic into
JdeScoping.ConfigManager.Core library. Add JdeScoping.ConfigManager.Cli
console app with validate, test-connection, and secret commands using
System.CommandLine. UI project now references Core for platform-agnostic
functionality while retaining Avalonia-specific dialog and clipboard services.
Add SqlServerPort property to connection string editor for explicit port
configuration, replacing the need to embed port in server name (e.g.,
localhost,1434). The port control generates the comma-separated format in
the connection string but does not parse it back when loading existing
connection strings.
Add comprehensive tests for services (ConnectionTestService, RuntimeConfigValidation),
ViewModels (PipelineEditor, dialogs, transformers), and Avalonia headless UI tests
for views and forms.
Eliminates placeholder substitution (${KEY}) in favor of storing complete
connection strings as single encrypted values. SecureStore now auto-creates
entries for all connection strings defined in appsettings. ConfigManager
editor reads/writes values directly to SecureStore.
Adds a new ConnectionStrings section to ConfigManager allowing users to manage
database connection strings with provider selection, connection testing, and
visual feedback for connection state.
