[Fix] Base Attack Context Menu

[WBHarry]

Fixes #1924
Fixes #1669

• Fixed Adversary standard attack context menu
• Fixed Character base attack context menu
• Fixed Companion base attack context menu

I only added in attack/damage/show-message as these are not things to edit or delete. The main benefit is the Damage option being available now.

Minor thing I also spotted - fixed so that adversaries do not display Object Object if the current Attack Damage is invalid

If the options are the same everywhere, protected method or actor folder helpers? The copy paste is fine now but if extended/fixed it'd be nice to avoid a desync.

Hm, yah they are strict al-dente copy pastas. Hm hm..

So I can easily just define a static method in the parent that all 3 of 'em use:

contextMenus: [
    {
        handler: DHBaseActorSheet.getBaseAttackContextOptions,
        selector: '[data-item-uuid][data-type="attack"]',
        options: {
            parentClassHooks: false,
            fixed: true
        }
    }
]

Dunno if I can really make it protected though, since it has to be statically available for static DEFAULT_OPTIONS 🤔

That should be fine.
