Refactoring of subscription panel to improve maintainability and match
Figma design exactly. Extracted business logic into
`useSubscriptionCredits` and `useSubscriptionActions` composables, added
comprehensive testing, and enhanced the design system with proper
semantic tokens.
- Extract credit calculations and action handlers into reusable
composables
- Add component and unit tests with proper mocking patterns
- Update terminology from "API Nodes" to "Partner Nodes"
- Make credit breakdown dynamic using real API data instead of hardcoded
values
- Add semantic design tokens for modal card surfaces with light/dark
theme support
- Reduce component complexity from ~100 lines to ~25 lines of logic
- Improve layout spacing, typography, and responsive behavior to match
Figma specs
