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.
Add CreateGiwConnectionAsync to IDbConnectionFactory and DbConnectionFactory
for connecting to the GIW Oracle database. This connection is needed for the
StatusCode data sync pipeline.
- Reuses existing CreateOracleConnectionAsync helper with "GIW" data source
- Follows same pattern as JDE, JDEStage, and CMS connections
- Includes 4 unit tests covering missing/empty/invalid connection strings
