fix: Theme dropped after page refreshing

[gt2345]

Description

Fix the issue that the theme selection is not persistent.
As soon as the page refreshes or reloads, it defaults to system settings.
This is because SettingsProvider and UIProvider were not properly wrapped.

Test Plan

Change system mode to light, then at the WebUI, switch the mode to Dark, refresh page, the theme should persist.
Change system mode to dark, then at the WebUI, switch the mode to Light, refresh page, the theme should persist.
Start server with RBAC, at the login page, HPE logo should be visible.
