MultiChannelStockLocationStrategy Fails to Clear Cached Channel IDs on StockLocationEvent

[dalyathan]

Describe the bug
MultiChannelStockLocationStrategy is not clearing cached channel ids on StockLocationEvent

Expected behavior
MultiChannelStockLocationStrategy should clear cached channel ids on StockLocationEvent

Environment (please complete the following information):

• @vendure/core version: 3.1.1
• Nodejs version 22
• Database (mysql/postgres etc): sqlite, mysql

Additional context
This should be
const channelIds = await this.channelIdCache.get(this.getCacheKey(stockLevel.stockLocationId),
since we are trying to clear cached channel ids by using this.getCacheKey(stockLocationId) in here
This should be

.subscribe(({ entity }) => this.channelIdCache.delete(entity.id));

Since Cache.delete expects id rather than the whole cache key.
