Name Textbox in Profile Menu Accepts Spaces and Special Characters

Describe the bug
The name textbox in the profile menu tab of the Enatega app/website is accepting spaces and special characters, which should not be allowed. The textbox should only accept valid characters, such as letters, and possibly specific symbols (e.g., apostrophes or hyphens).

To Reproduce

1. Open the Enatega app/website.
2. Go to the profile menu tab.
3. Click to edit the name field (e.g., during profile update).
4. In the name textbox, type a name with spaces or special characters (e.g., "@", "#", "!", etc.).
5. Observe that the textbox allows spaces and special characters as valid input.

Expected behavior

1. The name textbox should only accept valid characters such as alphabetic characters and, if necessary, a few special characters like apostrophes or hyphens.
2. Special characters (e.g., "@", "#", "!", etc.) and extra spaces should be rejected, ensuring proper data input.

Actual Behavior
The name textbox in the profile menu accepts spaces and special characters, which could lead to invalid or inconsistent data in the profile.

Smartphone (please complete the following information):

• Device: iPhone15pro

Search the profile menu implementation for the name textbox and reproduce the input problem on iOS and the website. Confirm the accepted character set with maintainers, then verify that disallowed symbols and extra spaces are rejected consistently on both platforms.
