[BWA-65] Sort items alphabetically with special char precedence

[SaintPatrck]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/BWA-65

Closes #167

📔 Objective

Adds a new comparator to sort items alphabetically, giving precedence to special characters over letters and digits. This comparator is used to sort items in the item search screen and the main item listing screen.

The comparator also gives priority to lowercase letters when comparing equal letters (e.g., 'a' comes before 'A').
