fix(chat): match the Create capsule's metrics to the bill step's Next

Create took the accent but not the proportions: grid.x3 horizontal padding
against Next's grid.x2, and a SemiBold label against Next's plain textMedium.
Side by side on the emulator that read as 10dp of extra width on an otherwise
identical pill. Both now match the currency creator's capsule exactly.
