feat(CDPSDK-2435): add SignEndUserEvmHashRule to TypeScript SDK

[sammccord]

Description

Add SignEndUserEvmHashRuleSchema to the TypeScript SDK policy schema for end-user EVM hash signing policy support.

• Added SignEndUserEvmHashRuleSchema to evmSchema.ts with action (ActionEnum) and operation (z.literal('signEndUserEvmHash')) — no criteria field, matching SignEvmHashRuleSchema pattern
• Exported SignEndUserEvmHashRule type
• Added SignEndUserEvmHashRuleSchema to the RuleSchema discriminated union in types.ts

Tests

Schema-only change with no runtime behavior change. All existing tests pass (546/546).

Checklist

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