fix: resolve all lint errors across codebase

- Convert CacheTTL enum to const object to fix duplicate value errors
- Fix import ordering in test files (eslint-disable for vi.mock pattern)
- Fix unused variable warnings (prefix with underscore)
- Auto-fix import ordering in subscription page, dashboard layout
- 0 lint errors remaining
