fix: TRX icon frame + carry over the HEZ/PEZ sharpening from main

TRX.svg used a full-bleed r=24 circle (no margin) instead of the r=18
padded-circle frame every other token icon uses, making it visually
inconsistent in the token list. Scaled its icon path down to fit the
standard frame instead of redrawing it.

Also brings HEZ/PEZ's sharper re-render (already pushed to main in 962daf7)
onto master, since master and main currently serve different assets to the
app (main/master divergence is a known, separately-tracked issue) and this
keeps both consistent for now.
