fix: bind actor context menu to v13 getActorContextOptions hook

Foundry v13 removed the v12-era getActorDirectoryEntryContext hook in the
ApplicationV2 sidebar migration, so registerContextMenu never ran and the
Add/Remove Omnipresence Sync items never appeared for any user. Switch to
the v13 get{DocumentName}ContextOptions paradigm (getActorContextOptions).
getDocumentId already handled v13's native HTMLElement/data-entry-id, so no
other change was needed. Verified live in Foundry v13 (menu absent before,
present after) and with a new hook-registration regression test.
