[FR]: user-configurable icons

[mateitudor]

Feature Description

The icons in TaskNotes are currently hardcoded so users can’t align them with their vault style.
Adding a settings tab or an icon section for the current relevant tabs where users can customize icons would be awesome. For instance the TaskNotes double checkmark is too distracting for me personally.

Scope should include:

• Ribbon actions
• View/tab icons
• Other user-facing UI icons (panels, dialogs, controls)
• Task states (in progress, done, etc.)

Thank you so much for this plugin, it and you are awesome!
