feat: update frxUSD and add mGLOBAL and redemption icons

[de-snake]

Changes

• Replace frxUSD artwork with the supplied SVG.
• Add the supplied mGLOBAL icon.
• Add frxusdredemptionfrommf-one.svg for frxUSD redemption from mF-ONE, with frxUSD top/front and mF-ONE bottom/back.

Verification

• Verified filename resolution with UI-kit 4.3.0.
• Inspected all three rendered assets in the in-app browser, including the redemption icon at 24px.
• SVG XML validation and git diff whitespace checks passed.

The filename matches the named symbol; live on-chain discovery of the new phantom token was not verified.
