[Feature Request] Add a Game Setting “Default Token Shape” for Gridless Scenes

[Kapuzenjoe]

Short Description
In Foundry’s current behavior, a token’s Shape is effectively determined by the scene’s grid type at the moment the token is created and isn’t reliably preserved or applied via the actor’s Prototype Token configuration.
On gridless scenes, many tables prefer circular tokens (Ellipse) for readability, but the default creates tokens as Rectangles - meaning you have to change the Shape manually for every newly dragged token, which becomes tedious very quickly. The system should provide sensible default Shape types per grid type (e.g., Rectangle for square grids, appropriate variants for hex grids), but gridless has no clear rules-based recommendation - so a user-configurable preference is needed.

Proposed Solution
Add a DnD5e game setting: “Default Token Shape (Gridless Scenes)” with options matching Foundry’s gridless shape (e.g., Ellipse / Rectangle). When a token is created or dragged onto a gridless scene, DnD5e should automatically apply this configured default.
For square and hex scenes, keep the default behavior system-managed (no additional settings), since the grid semantics already define the expected token footprint.
