Refactor and enhance DbContext configuration

Updated `AddRecInfrastructure` to improve DbContext setup:
- Renamed parameters for clarity (`dbContextOpt` to `opt`).
- Renamed `connectionString` to `cnnStr` for consistency.
- Added `LogTo` for SQL query logging at `Trace` level.
- Enabled `EnableSensitiveDataLogging` for debugging.
- Enabled `EnableDetailedErrors` for detailed error messages.
