Drink Beer Rebrew

First Fabric release of this fork.

Fixes six upstream bugs, four of which break the mod on NeoForge too (bartending table crashed on the first spice; the "drunk frost walker" effect was removed on its first tick; blocks dropped nothing when mined; the game crashed on the first player save after a cocktail). Plus: the beer can now be taken off the bartending table, and cocktail names no longer render as raw translation keys.

Server-side behaviour is covered by an automated pass on a real Fabric server (tools/prod-test.sh); client-side testing is still in progress, hence beta.
