Update primevue dependency

Update the primevue dependency. Creating this as a separate task because it needs significant testing to ensure nothing breaks.

Current known issues to check for specifically:

- https://github.com/getodk/web-forms/issues/469
- https://github.com/getodk/web-forms/issues/467
- https://github.com/getodk/web-forms/pull/666/changes#r2830978276

Start by reviewing the PrimeVue dependency configuration and the three linked issues and pull-request discussion. Exercise the affected form flows and check the referenced problems for regressions. Done means the dependency is updated and the known issues remain resolved without breaking form filling or submission editing.
