feat: update plugin-sdk-go dependency and enhance BDD scenario manage…

[pikann]

This pull request introduces activity tracking for BDD scenario lifecycle events in the backend, updates the plugin SDK version, and refactors the frontend to use a new API client abstraction for BDD scenario operations. It also removes the BDDScenarioCard component from the frontend and introduces utility and API helper functions.

Backend improvements:

• Added activity recording for BDD scenario creation, update (including tracking changed fields), and deletion in scenarios.go to improve auditability and user feedback. [1] [2] [3] [4]
• Upgraded the dependency on plugin-sdk-go from v0.2.0-rc.3 to v0.2.0-rc.5 in go.mod for compatibility and new features.

Frontend refactoring:

• Removed the BDDScenarioCard component, likely as part of a UI redesign or migration.
• Added lib/interaction-api.ts with helper functions for BDD scenario CRUD operations using the new PluginApiClient abstraction, improving code reuse and maintainability.
• Added a cn utility function for conditional class name concatenation in lib/utils.ts, centralizing a common pattern.

Other changes:

• Updated the plugin version from 0.1.0 to 0.2.0 in plugin.json to reflect new features and improvements.
