Add new securities and use real prices in FIX UI order entry

- securities.txt: add EUROB, AEG, INTKA, AAAK, ATTIK to existing symbols
- fix-ui-client: load securities as {symbol: price} dict so prices flow through
- index.html: auto-populate price field from current security price on symbol change
- oeg_simulator: read symbols and prices from securities.txt instead of hardcoded FOO/AAA/BBB at ~100
