fix(FR-2805): correct tab key and use URLSearchParams in deployment preset navigation (#7233)

Resolves #7232 ([FR-2805](https://lablup.atlassian.net/browse/FR-2805))

## Summary
- Fix typo in the tab query parameter when navigating back from `AdminDeploymentPresetSettingPage` (`deployment-preset` → `deployment-presets`), which is the key actually registered in `AdminDeploymentListPage`.
- Build the navigation URL with `URLSearchParams` instead of string concatenation for safer query handling.

## Test plan
- [ ] Create a deployment preset → after save, the list page opens on the **Deployment Presets** tab.
- [ ] Edit a deployment preset → after save, the list page opens on the **Deployment Presets** tab.
