Use native types instead of SDK types

[fmorency]

We're querying the server REST endpoint which returns SDKType.

The SDKType generated by Telescope breaks the TS typing with numerical enums, e.g., ProposalStatus. The query will return the string field equivalent instead of the numerical value, even if the SDKType generated by Telescope expects the numerical value.

We should use native types instead.

Sadly, enabling toSDK and fromSDK in ManifestJS is not enough. Nested Any from the x/group module is broken.

This is a Telescope issue.

is this currently breaking anything in the ui?

No, this is something to be done in the future once Telescope is fixed.
