Epic Fight Guard Fix

Tools + shield: fixed a regression from the pickaxe/shovel/hoe interaction fix

• The earlier fix that stopped pickaxes/shovels/hoes from breaking chest/block interaction (see prior changelog) had an unintended side effect: it also disabled guardfix's entire shield-combo treatment for that combo, so equipping a shield alongside a pickaxe/shovel/hoe silently did nothing at all.
• Now a shield in the offhand alongside one of these tools gets the full treatment again (guard/parry, free stamina, penalty reset, passive buff) — block/chest interaction with the tool alone (no shield) is still unaffected by this.

Shield pose for weapons with no guard animation of their own

• Some items guardfix makes shield-eligible (pickaxes and similar) don't have their own "block" animation registered anywhere, so blocking an attack negated the damage correctly but showed zero visual feedback — looked exactly like the shield wasn't working even though it was.
• These now show the same raised-shield pose bare-hand + shield already uses, correctly held in the off hand where the shield actually is. Weapons that already define their own block pose are unaffected.
