fix(ui): prevent collapsed avatar clipping

[azizbecha]

What is this PR about?

Prevents the account avatar from being clipped when the sidebar is collapsed. Collapsed padding is now assigned by button size, so default and small icon buttons keep their padding while the large account button reliably uses zero padding around its 32px avatar.

Greptile Summary

This PR adjusts collapsed sidebar button padding according to button size.

• Preserves 8px collapsed padding for default and small buttons.
• Removes collapsed padding from large buttons so the 32px account avatar fits within its 32px container.

Confidence Score: 5/5

The PR appears safe to merge, with the size-specific padding behavior matching all current sidebar button callers.

All current callers use default, small, or large size variants; default and small preserve their previous collapsed padding while the large account button intentionally removes padding to fit its avatar.
