Fix MUD0002 analyzer warnings on MudIconButton Title attribute

[phmatray]

Summary

The Title attribute on MudIconButton triggers MUD0002 warnings in the MudBlazor analyzer. This is a pre-existing pattern across the codebase, not introduced by #20.

Context

MudBlazor's analyzer flags Title usage on MudIconButton as deprecated or incorrect (MUD0002). Multiple components use this pattern and should be updated to the recommended alternative.

Acceptance Criteria

• Identify all MudIconButton usages with Title that trigger MUD0002
• Replace with the MudBlazor-recommended approach
• Zero MUD0002 warnings in build output
