Settings: Search fancy zone settings and swallow the ctrl+f event (#41437)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
This pull request primarily improves the maintainability and robustness
of the FancyZones settings UI by assigning unique `Name` attributes to
`SettingsCard` controls in the `FancyZonesPage.xaml` file. Additionally,
it enhances the logic for retrieving element UIDs and improves fallback
behavior for missing localizations. There is also a minor usability fix
in the shell page to prevent unintended navigation when focusing the
search box.

**FancyZones settings UI improvements:**

* Added unique `Name` attributes to all `tkcontrols:SettingsCard`
elements in `FancyZonesPage.xaml` to facilitate easier referencing and
future maintainability. This affects all relevant settings groups and
controls in the file.

**Element UID retrieval and localization:**

* Improved `GetElementUid` in `Program.cs` to fall back to the first
child's `x:Uid` if the element itself lacks one, increasing robustness
when parsing XAML.
* Updated `GetLocalizedSettingHeaderAndD` in `SearchIndexService.cs` to
provide a fallback for missing localizations by trying the
`"{elementUid}/Content"` resource key.

**Shell page usability:**

* Modified `CtrlF_Invoked` in `ShellPage.xaml.cs` to mark the event as
handled, preventing unintended navigation when the search box is focused
with Ctrl+F.
