fix AutoOmen constant mode double drinking

[AeiouJx]

Problem

When AutoOmen finishes drinking an ominous bottle, it immediately starts drinking a second one on the same tick, consuming two bottles per cycle instead of one.

Root cause

In AutoOmen.handleClientTick(), the drink-completion branch (if (isEating)) only reset the constant timer, then fell through to doInventoryActionsV2(). The bottle was still equipped, so it returned ITEM_IN_HAND and re-invoked startEating(), beginning another drink right away.

Fix

Finalize the drink state and return early after a completed drink instead of falling through and starting a second drink:

if (isEating) {
    isEating = false;
    // we completed eating successfully
    constantTimer.reset();
    return;
}

remove, no need to block inv actions at this point

remove, is already false now
