refactor: overwritable settings config

[Schwehn42]

Description

The last couple of refactors concerning the settings dialog (#4265) were a great upgrade allowing for configuration of settings items, including name, color etc. as well as when these are enabled (settings were only used on boards before, now they're also available for every other route).

While this is quite convenient, the menu items themselves are still constant, with the only possibility to toggle which ones are displayed, but not for the properties themselves.

Hence, with this PR it's now also possible to override settings at runtime by passing an override prop to the SettingsDialog component.

Example

<Route path="settings" element={<SettingsDialog 
  enabledMenuItems={{...ENABLE_ALL, feedback: feedbackEnabled}}
  overwrite={{appearance: {color: "goal-green"}}} />}
>
  <Route path="appearance" element={<Appearance />} />
  {/* other settings routes here */}
</Route>

Changelog

• add new prop ?overwrite of new type MenuItemConfigOverride to SettingsDialog
• add typesafe function to merge with MENU_ITEM_CONFIG
• internal changes to SettingsDialog where the merged config is used as state in order to render the settings

Checklist
