beacon: add production breakdown panel showing per-building resource contributions

Players can now see exactly which buildings contribute to each resource
rate, including Timmy harmony bonuses, Bilbo randomness, Allegro trust
penalties, and passive generation. Appears once 2+ buildings are built.

Also includes minor fixes:
- Production bars sort by absolute contribution (negative rates visible)
- Delta calculation catches passive sources (ops from users, Pact trust)
