Introduces 'workedViaSatellite' status to DXCC tracking in both controller and model, including batch queries for satellite contacts. Updates the DXCC list view to show a badge when a country has been worked via satellite, improving visibility of satellite achievements.
Updated SQL queries in Workabledxcc controller and model to use case-insensitive matching for DXCC country names by comparing UPPER(COL_COUNTRY) to UPPER(?). This resolves issues where country names with different cases were not matched correctly.
Refactored Workabledxcc controller and model to batch DXCC entity and worked/confirmed status lookups for improved performance. Added migration to create composite indexes on DXCC-related columns to further speed up queries. Updated migration version to 205.
