fix(psalm): improves code quality and adds safety checks

Adds checks for array and content validity to prevent potential errors.
Also, it ensures icon HTML is properly handled in share links and sprite names are correctly parsed.
The Psalm configuration is updated to suppress missing dependency errors and introduce stricter type checking.
