Restrict placing items in barrels except for alcohol and add CoreProtect compatibility

[BAD7777]

Hello! I would like to suggest an enhancement for the BreweryX plugin.

Problem:

Currently, players can place not only alcohol but also other items into barrels. This can lead to bypassing CoreProtect logging, as items inside barrels are not properly tracked, creating potential risks for server administrators.

Suggestion:

1. Restrict placing any items in barrels except alcohol. This will improve security and prevent barrels from being used to store other items.

2. Add CoreProtect compatibility, so all barrel interactions (adding/removing items) are logged in CoreProtect and are available for administrators for monitoring and auditing purposes.

Expected Outcome:

• Barrels will only store alcohol.
• No other items can be placed in barrels.
• All barrel interactions will be logged in CoreProtect logs (if the plugin is installed).
