feat(backend): port route-planning backend to Go

Add a Go implementation mirroring the Python pipeline (loader, graph,
pathfinder, arbitrage, market, route, manager) under internal/core, with
ESI client/API integration and setup endpoints. Reuses backend/src as
the working directory so existing data/cache paths keep working.
