Fixes table source subheaders remaining displayed during filtered search in Item Tables. (Thanks to Death_Stapler for reminding me that the `:has(td)` selector works in JS, too.)
Adds Actor data context to Item Tables during `createActor` hook event.
Adds support for string ancestry names in Edge requirements checks.
Edge requirements check no longer requires the Actor to have an ancestry first.
Fixes error when an `species` string is used instead of an ancestry Item and attempting to toggle Adaptable.
