test: migrate as unknown as to @total-typescript/shoehorn (#10761)

*PR Created by the Glary-Bot Agent*

---

## Summary

- Replace all `as unknown as Type` assertions in 59 unit test files with
type-safe `@total-typescript/shoehorn` functions
- Use `fromPartial<Type>()` for partial mock objects where deep-partial
type-checks (21 files)
- Use `fromAny<Type>()` for fundamentally incompatible types: null,
undefined, primitives, variables, class expressions, and mocks with
test-specific extra properties that `PartialDeepObject` rejects
(remaining files)
- All explicit type parameters preserved so TypeScript return types are
correct
- Browser test `.spec.ts` files excluded (shoehorn unavailable in
`page.evaluate` browser context)

## Verification

- `pnpm typecheck` ✅
- `pnpm lint` ✅
- `pnpm format` ✅
- Pre-commit hooks passed (format + oxlint + eslint + typecheck)
- Migrated test files verified passing (ran representative subset)
- No test behavior changes — only type assertion syntax changed
- No UI changes — screenshots not applicable
