Add Ethereum and Plasma USDT funding support

[shreyav]

Summary

Extends stablecoin funding capabilities to support USDT on Ethereum L1 and Plasma networks, and updates USDC support on Ethereum to explicitly include USDT as an alternative asset type.

Changes

• Internal Accounts Documentation: Added new "Ethereum Stablecoin Funding" accordion section with example JSON for funding Ethereum L1 wallet accounts with USDT
• Account Types Reference:
  • Updated ETHEREUM_WALLET to support both USDC and USDT (previously USDC only)
  • Added new PLASMA_WALLET account type for USDT funding
  • Updated documentation to reflect these changes across multiple sections
• OpenAPI Specs: Updated cryptoNetwork field descriptions in RealtimeFundingQuoteSource to include TRON and PLASMA as example values
• Skill Documentation: Updated compatible instant methods to reflect USDT support on Tron, Ethereum, and Plasma networks

Implementation Details

All changes are documentation-only updates to OpenAPI schemas and Mintlify MDX files. The OpenAPI source files in openapi/components/schemas/ were updated, and make build should be run to rebundle the generated openapi.yaml files.
