test: provide a testing Pinia by default (#15057)

## Summary

- create a fresh `createTestingPinia({ stubActions: false })` before
each root and desktop UI test
- remove 207 redundant per-suite activations
- retain 11 explicit activations needed for module initialization,
mid-test resets, and property-based iteration isolation
- leave specialized suites free to replace the active Pinia with real
Pinia, stubbed actions, plugins, or custom spies

Stacked on #15053.

## Verification

- root Vitest suite: 15,896 passed, 8 skipped across 1,159 files
- desktop UI Vitest suite: 125 passed across 16 files
- `pnpm lint`
- `pnpm typecheck`
- formatting and commit hooks
