Fix saved view deletion

[ejsmith]

Summary

• Clear saved-view query params through a helper that respects the current route's supported params.
• Avoid assigning unsupported filters, saved, or sort keys while clearing the active saved view.
• Add unit coverage for both full saved-view query state and route-limited query state.

Why

Deleting an active saved view first clears the selected view state. Stack/event routes do not define every optional saved-view query key in kit-query-params, so assigning unsupported keys caused the clear path to throw before the delete flow could finish, leaving the confirmation dialog open.

Validation

• npm run test:unit -- src/lib/features/saved-views/use-saved-views.test.ts --run
• Local Aspire browser repro: created and deleted a disposable saved stack view; the confirmation dialog closed, navigation returned to /next/stack, and the API returned 404 for the deleted saved view.

Breaking changes

None.
