feat(CDPSDK-2384): add SendEndUserEvmAsset and SendEndUserSolAsset rule support

[sammccord]

Description

Adds SDK support for SendEndUserEvmAssetRule and SendEndUserSolAssetRule in both TypeScript and Python SDKs. These new policy rule types allow controlling end-user EVM and Solana asset operations, with support for the RateLimiting criterion unique to Asset rules.

Closes CDPSDK-2384.

Changes

• openapi.yaml: Updated with latest generated spec including Asset rule schemas
• TypeScript: Added Zod schemas (SendEndUserEvmAssetCriteriaSchema, SendEndUserEvmAssetRuleSchema, SendEndUserSolAssetCriteriaSchema, SendEndUserSolAssetRuleSchema, RateLimitingCriterionSchema), added to RuleSchema discriminated union, regenerated OpenAPI client
• Python: Added Pydantic models (RateLimitingCriterion, SendEndUserEvmAssetRule, SendEndUserSolAssetRule), added to Rule union, updated request_transformer.py and response_transformer.py with full criterion mappings using correct CriteriaInner wrapper types, regenerated OpenAPI client

Tests

• TypeScript: 6 new tests in policies.test.ts — EthValue/RateLimiting criteria for EVM Asset, SolAddress/RateLimiting criteria for SOL Asset, schema validation rejection tests. All 501 tests pass.
• Python: 8 new tests in test_policies_client.py — 4 async create_policy tests (EthValue/RateLimiting for EVM, SolAddress/RateLimiting for SOL) + 4 transformer round-trip tests. All 722 tests pass.

Checklist

• Updated the typescript README if relevant
• Updated the python README if relevant
• Added a changelog entry
• Added e2e tests if introducing new functionality
