DxFeed sync: Phidias Prop Firm and SwissFirmUp

Phidias Prop Firm and SwissFirmUp are now available in the Prop firm dropdown when you connect a DxFeed account. Pick your firm first, then sign in with the same email and password you use on their platform.

Trades are pulled from each firm's own history server, so your import lands in the right place without manual CSV work. If you trade with either firm, open Connect DxFeed Account from account settings and select it from the list.
