fix(caip): add input validation to createCaip10AccountId

[ak68a]

Summary

• Validate chainId against caip2ChainIdRegex and address against caip10AccountAddressRegex before creating the account ID
• Add test cases for invalid inputs

createCaip10AccountId previously performed no validation, allowing malformed chain IDs and addresses to propagate silently. The regex patterns were already defined in the module but not being used. This brings the function in line with caip10Parts(), which already validates its input.

Test plan

• Existing CAIP tests pass
• New tests verify rejection of invalid chain IDs and addresses
