Add Plasma (PLASMA_WALLET) to Grid public API schema

[ls-bolt]

Summary

Adds the public Plasma wallet type to the Grid API, mirroring the existing Tron wallet. Plasma is an EVM chain, so wallets use 0x addresses and the asset is USDT.

Changes

• New schemas: PlasmaWalletInfo, PaymentPlasmaWalletInfo (asset USDT), PlasmaWalletExternalAccountInfo
• PLASMA_WALLET added to PaymentAccountType and ExternalAccountType
• PLASMA added to CryptoNetwork
• PLASMA_WALLET wired into the external-account and payment-instructions discriminator unions
• Plasma stablecoin-funding example added to the internal-accounts docs snippet
• .stainless/stainless.yml synced; make build rebundled openapi.yaml + mintlify/openapi.yaml; make lint-openapi clean

Draft: this is the public surface for USDT-on-Plasma and lands only when we choose to expose Plasma to integrators. The webdev client is regenerated from this schema in a companion PR.

⚡ Heads up on the red Detect breaking changes check — this is expected and by design for adding a new wallet type. All 45 findings are response-property-one-of-added: PaymentPlasmaWalletInfo / PlasmaWalletExternalAccountInfo being added to the accountOrWalletInfo / accountInfo response oneOf unions (funding instructions, external accounts, transactions). It's the same additive-union change that adding Tron/Base/Polygon would have flagged — nothing is removed or narrowed.

The workflow's design is to label such PRs breaking-change and require an API-reviewer's sign-off rather than hard-block, which fits how we're treating this: the PR stays a draft and is held until we decide to expose Plasma publicly. Flagging for the API reviewer to confirm whether this rides the current API version or warrants a version bump when it ships.
