[PS-1352] Fix ignore diacritics in search

[noncenz]

This change updates the search function to ignore diacritical marks in search results. Marks are stripped from both the search input and results.

Type of change

• [X] Bug fix
• [ ] New feature development
• [ ] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
• [ ] Build/deploy pipeline (DevOps)
• [ ] Other

Objective

Fixes #2008

Search results should match on base characters, ignoring any accents or other glyphs applied to the search term or the stored data.

Code changes

/src/Core/Utilities/StringExtensions.cs - Added new file to contain String extension to normalize strings by removing diacritics.

/src/Core/Services/SerachService.cs - Applied String extension to search term, item name and item subtitle.

Before you submit

• [X] I have checked for formatting errors (dotnet tool run dotnet-format --check) (required)
• [ ] I have added unit tests where it makes sense to do so (encouraged but not required)
• [ ] This change requires a documentation update (notify the documentation team)
• [ ] This change has particular deployment requirements (notify the DevOps team)

@noncenz thank you for your contribution. Your work is good to go. I've decided to just clean up the dev logging and add a validation. This will be included in a future mobile release.
