refactor: remove Python sidecar from C# projects

- Delete PythonSidecarAiService, PythonSidecarSpeechService, PythonSidecarClient
- Remove PythonExecutable, PythonAiSidecarPath, AiSidecarTimeoutMs from JournalConfig
- Remove python-sidecar as valid AiProvider (only none/llamasharp remain)
- Simplify DI: default IAiService is DisabledAiService, ISpeechBridgeService is disabled
- Remove python-sidecar fallback from Journal.AI ServiceCollectionExtensions
- Remove 5 Python sidecar smoke tests and BuildAiConfig helper
- Remove Python config assertions from TestConfigServiceParityKeysAsync
