feat: add project key support for Jira analytics

- Introduced `projectKey` and `ignoredProjects` fields in Jira configuration to enhance analytics capabilities.
- Implemented project validation logic in `JiraConfigClient` and integrated it into the `JiraConfigForm` for user input.
- Updated `IntegrationsSettingsPageClient` to display analytics dashboard link based on the configured project key.
- Enhanced API routes to handle project key in Jira sync and user preferences.
- Marked related tasks as complete in `TODO.md`.
