Incorrect horizons flag in EDDN messages from CAPI updates

[HansAcker]

Please complete the following information:

• Version: 5.11.2
• Game Version: Live Horizons
• OS: Win 10
• OS Locale: eng

Commodity market updates from CAPI in Live-Horizons in some cases produce messages with horizons: false, odyssey: false. Often seen at fleet carriers and planetary outposts, not at space stations.

It looks like capi_is_horizons() incorrectly returns false when a station offers no ships or modules and has no Colony economy? I don't quite follow the logic, tbh.

To Reproduce

1. Log into Horizons (Live)
2. Dock to a fleet carrier
3. Often, this already produces a market message with horizons: false
4. Re-log
5. That reliably produces a Location message with horizons: true and a market update with horizons: false
6. Updating market.json produces a message with the correct flags

Additional context

Messages after logging into Horizons while docked at a carrier. Location:

Market update from CAPI with both flags set to false:

Correct flags on event from local file:

Market update at a station with shipyard and outfitting:

It looks like capi_is_horizons wasn't updated for the universe split or for carriers. I wonder if there are any cases even in the legacy universe where someone can have no access to Horizons?
