Able to add similar names without warning about duplicates

[linette-g]

The current duplicate detection in the name field is case-sensitive and does not ignore whitespace. This results in duplicate entries when names are entered with different cases or slight variations in spacing (e.g., "John Doe" vs. "john doe" or "John Doe" with extra space). Typically, name matching in real-world applications is case-insensitive and should account for variations in whitespace to avoid redundant entries. A suggested improvement is to add a warning message when such cases occur to remind the user of the potential duplicate.
