### What changes were proposed in this pull request? This PR aims to fix `SparkConnectClient.getConf`, `getConfWithDefault`, `getConfOption` and `isModifiable` to not crash when the server returns a `ConfigResponse` with no pairs. - `getConf` throws `SparkConnectError.sqlConfNotFound`. - `getConfWithDefault` returns the given default value. - `getConfOption` returns `nil`. - `isModifiable` returns `false`. ### Why are the changes needed? These methods read `response.pairs[0]` without a bounds check, so an empty response traps with an index-out-of-range error and crashes the client process. ### Does this PR introduce _any_ user-facing change? Yes, it fixes a bug. An empty `ConfigResponse` used to crash the process. Now it is handled as described above. ### How was this patch tested? Pass the CIs with the newly added test case (`SparkConnectClientTests.getConfValue`). The other three methods are not covered because an empty server response cannot be simulated without a mock server. ### Was this patch authored or co-authored using generative AI tooling?
