[UI] Main dashboard button graphics redesign

[HuckleR2003]

Milestone: v1.7.0

Problem: Dashboard buttons functional but visually boring.
Goal: Professional look without sacrificing performance.

Constraints:

• Zero FPS impact (pre-render gradients, reuse objects)
• Layout unchanged (buttons stay same size/position)
• Maintain current color scheme (purple primary)

Tech:

• PIL for gradient generation (done once on init)
• Canvas caching for button states
• CSS-like hover system with state tracking

Hey! Another goal behind PC Workman.
Just closed #15 with the latest dashboard button redesign.

I went through the whole set of buttons on the main dashboard and gave them a proper visual upgrade while keeping all the constraints:

• Zero FPS impact
• Same size and position
• Still using the purple primary scheme

They now look much more polished and modern without feeling overdesigned.
Simple gradients, hover states and overall, just on another level.
