Moves the canonical SpaceType + SPACE_MODULE_ALLOWLIST to @mana/shared-types
(framework-free) so the Bun services can consume them without pulling in
Svelte. shared-branding keeps only the UI-facing labels and descriptions
and re-exports the canonical types for frontend convenience.
Wires two Better Auth organization hooks in mana-auth:
- beforeCreateOrganization asserts metadata.type is a valid SpaceType,
rejecting the create with a BAD_REQUEST otherwise.
- beforeDeleteOrganization rejects deletion of the personal space.
Covered by bun tests (11 assertions) for the helper module.
No migration and no schema change — type lives in the existing
organization.metadata jsonb column.
