Add SonarQube coverage integration and UI; improve template request logging and redaction

[Idddd]

Motivation

• Add a SonarQube coverage assistant to surface project coverage, list uncovered files, and optionally generate missing tests using the configured LLM.
• Provide a convenient UI in the AI Context Box and a Tools action to inspect SonarQube results and jump to source lines.
• Harden LLM template HTTP request logging to avoid leaking sensitive headers and payloads and improve error messages for unauthorized responses and missing JSONPath extractions.
• Expose SonarQube settings in configuration and documentation so users can enable the new feature.

Description

• Added SonarQube configuration support (SonarQubeConfig) to AiTestConfig and parsing in LlmSettingsLoader with helper converters for double and int, and loadSonarQubeConfig accessor.
• Introduced a new tool window panel SonarCubeToolWindowPanel and a SonarQubeCoverageAction (with dialog, client, data models, renderer, prompt builder) to fetch measures and issues, display a summary, list uncovered files, and build prompts to generate missing tests using the LLM; registered the action and tool window tab in plugin.xml and added a prompt template SONARQUBE_MISSING_TESTS in AiPromptDefaults.
• Enhanced TemplateRequestExecutor to set a default Content-Type when missing, redact sensitive headers and payload values from logs, truncate long bodies, include safe response summaries in error messages, and throw an explicit LlmUnauthorizedException on 401 responses; improved log messages to include responsePath on failures.
• Added ContextBoxStateService.recordSonarQubeCoverage to record SonarQube results into the AI Context Box and wired the Sonar tab into ContextBoxToolWindowFactory; installed a runtime log sink in LlmAuthSessionService to route runtime logs into RuntimeLogStore; updated README with SonarQube configuration sample and usage notes.

Testing

• No automated tests were added or executed as part of this change.
