Fen's RPG Titles

Fixed title rendering alignment by drawing titles inside the vanilla EntityRenderer.renderNameTag transform (mixin), so the title always follows the nametag’s exact pose stack.

Ensured title offset uses nametag text space (line height + small gap) for consistent “just above the name” spacing.

Added client cleanup on logout to prevent titles carrying over between worlds.

Fixed /rtitle revoke to immediately clear the displayed title for all clients when a revoked title was active.
