Bug Fixes: Loot, Rewards, Training, and Weekly Tasks

## Bug fixes - Blood Beasts now drop Poisoned Fang, so the item can be collected for the weekly delivery task. - Fixed daily-reward resting-area status updates that could be missing or stale when a character's protection-zone state changed. Stamina and soul regeneration timers now stop when the required streak bonus is no longer active. - Players actively attacking a Target Dummy monster can now regenerate 1 stamina every 5 minutes while they remain targeted, up to the normal stamina cap. This applies to monster-based training and does not refer to item-based exercise dummies or exercise weapons. - Excluded these currently identified inaccessible creatures from mainland weekly tasks: Dawnport's Muglex Clan Assassin and Muglex Clan Footman; Newhaven's Corrupted Ghost, Corrupted Skeleton, The Corruptor, and Muglex Clan Chief. This is the current identified subset; additional inaccessible creatures may still be audited separately.
