Wire Syndicate action card resolve button

[wholton]

Summary

• SyndicateAcd2ButtonHandler defines @ButtonHandler("resolveSyndicate"), but ActionCardHelper had no branch for automationID = "syndicate", so playing the card never emitted its resolve button. This wires up the button next to the other acd2 cards (e.g. ubiquity).

Why

• Every other automated action card is wired up via an if ("<automationID>".equals(automationID)) block in ActionCardHelper.playAsAction. Syndicate slipped through — the handler shipped without a corresponding emission site, so Play Syndicate produced no follow-up button.

Scope check

• I audited every acd2 card. This is the only card where a handler exists but no play-time button is emitted. Riders (classified_rider, defense_rider) and amendment correctly emit from AgendaHelper / StartPhaseService per their windows. The rest of the missing IDs have no handler code at all (out of scope for this fix).

Test plan

• Play Syndicate as an action; a Resolve Syndicate button appears.
• Pressing it reveals N cards (N = real player count) and produces per-player assign buttons.
• Assigning cards routes each to the target player and clears state when done.
