feat: Add leaderboard and stats UI for minigames

- Implemented MinigameLeaderboardUIService to manage the leaderboard UI.
- Created MinigameLeaderboardUISystem to handle UI updates.
- Added methods in MinigameStatsService and MinigameStatsRepository for fetching top players and distinct dimension values.
- Introduced new commands for accessing minigame stats in the command language.
- Added tests for minigame interactions and ensured proper decoding of interaction fields.
- Refactored MinigameRuntimeEffect to utilize MinigameActionContext for better context handling.

 A Hytale-native minigame extension for server-side minigame definitions, runtime state, and trigger-volume logic.
 
-The mod mirrors Hytale's own asset and trigger systems instead of maintaining a separate minigame-only registry layer. Minigames are `MinigameDefinition` assets, trigger logic is registered as real `TriggerEffect` and `TriggerCondition` codec entries, and runtime events are dispatched on Hytale's event bus.
+The mod mirrors Hytale's own asset, trigger, and interaction systems instead of maintaining a separate minigame-only registry layer. Minigames are `MinigameDefinition` assets, trigger logic is registered as real `TriggerEffect` and `TriggerCondition` codec entries, item/entity/NPC actions can use real `Interaction` entries, and runtime events are dispatched on Hytale's event bus.
 
 ## Features
 
 - Asset-driven minigame definitions in `Server/Minigames/`
 - Hytale Asset Editor support through `MinigameDefinition.CODEC`
 - Hytale trigger-volume integration through native `TriggerEffect` and `TriggerCondition` types
+- Hytale interaction integration through native `Interaction` types for item/entity/NPC use actions
 - Asset-backed `MinigameId` picker fields in the trigger-volume editor
+- Asset-backed minigame trigger-volume templates in `Server/MinigameVolumeTemplates/`
 - Runtime lifecycle commands for creating, enabling, starting, stopping, and resetting minigames
 - Multi-map runtime support using Hytale trigger-volume tags
 - Player, team, score, lives, counter, status, and phase runtime state

 For multi-map minigames, tag volumes with `MinigameId=<id>`, `MapId=<map>`, optional `VariantId=<variant>`, and `MapRole=MainArena` on the primary arena volume. Team spawn volumes use `SpawnRole=TeamSpawn` and `TeamId=<team>`. `MapSelectionMode` controls whether a queued match uses votes or random selection.
 
+To bootstrap common logic, spawn editable template volumes at your position:

+trigger volumes with template tags replaced by the provided IDs.

+## Interaction Logic
+
+Many minigame effects also have Hytale interaction counterparts. Interaction type IDs use the `Minigame` prefix plus the trigger effect ID, for example `MinigameJoinMinigameQueue`, `MinigameModifyScore`, and `MinigameOpenMinigameQueueUI`.
+
+Interaction-backed minigame actions use Hytale root interaction cooldown and chaining fields instead of trigger-volume `Event`, `Interval`, and `Delay`. Common routing fields are `MinigameId`, optional `MapId`, optional `VariantId`, and optional `TeamId`.
