Transforms the subscription credits panel from legacy design to
tier-based layout with Creator tier details, updated typography using
design system tokens, improved responsive credit breakdown layout, and
better subscription management flow. Updates credit formatting to remove
unnecessary decimals and Credits suffix, replaces external Stripe
billing portal with inline dialog, and reorganizes plan benefits section
with proper v-for structure matching Figma specifications.

## Summary
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
