Added a util helper to remove accent and case to improve search logic (#14533)

# [WIP] Make Local Search Non-Accent-Sensitive

fixes(#14468)

---

**Description:**  
This PR adds accent- and case-insensitive search for the
**SettingsWorkspaceMembers** component’s local search. It ensures that
searching for names or emails works correctly even if the user types
letters without accents.

**Implementation:**  
- Added a helper util: `removeAccentsAndCase(text: string)`  
- This util:
  - Normalizes text to NFD form
  - Removes diacritics (accents)
  - Converts text to lowercase
- Replaced current `.includes(searchFilter)` logic with a normalized
comparison:
