Add game tests for all mod advancements

[Copilot]

Implements game tests to verify all advancements in ColossalChests can be obtained through the correct in-game mechanics as defined by their advancement JSON files.

New Tests (16 total)

• testAdvancementRoot — fires INVENTORY_CHANGED trigger with a chest item
• testAdvancementUncolossal — ServerPlayer places uncolossal chest, triggering placed_block
• testAdvancementBase{Material} × 7 — builds a 2×2 chest with one wall missing, ServerPlayer places the final wall block, completing the chest and firing chest_formed
• testAdvancementSize{Material} × 7 — same pattern but with a 10×10×10 chest (filling the existing empty10 template), satisfying minimumSize: 10

New Helpers

// Centralizes @SuppressWarnings("removal") for the deprecated API
private ServerPlayer makeMockServerPlayer(GameTestHelper helper) { ... }

// Triggers full block-placement mechanics (setPlacedBy → triggerDetector → criterion trigger)
private void placeBlockAsServerPlayer(GameTestHelper helper, ServerPlayer serverPlayer, BlockPos pos, Block block) { ... }

// Looks up advancement by ResourceLocation and asserts isDone()
private void assertAdvancementDone(GameTestHelper helper, ServerPlayer player, ResourceLocation advancementId) { ... }

All tests exercise the real trigger chain — placing a block as a ServerPlayer goes through BlockItem.place() → setPlacedBy() → triggerDetector() → criterion trigger → advancement grant — rather than firing triggers directly.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
