feat: add contact properties

[Cisneiros]

Summary by cubic

Adds SDK support for managing contact properties with create, list, get, update, and delete methods. Normalizes API snake_case to SDK camelCase and provides type-safe request/response interfaces.

• New Features
  • ContactProperties class: create, list (with pagination), get, update, delete.
  • API↔SDK parsing utils (fallback_value ↔ fallbackValue); list/get return SDK types.
  • Type definitions for ContactProperty and request/response payloads.
  • Update validation: returns an error when id is missing.

<file name="src/contact-properties/interfaces/create-contact-property-options.interface.ts">

<violation number="1" location="src/contact-properties/interfaces/create-contact-property-options.interface.ts:20">
CreateContactPropertyApiOptions should preserve the correlation between type and fallback_value; the current union allows number properties to carry string fallbacks (and vice versa), leading to invalid API payloads.</violation>
</file>

<file name="src/common/utils/parse-contact-properties-to-api-options.ts">

<violation number="1" location="src/common/utils/parse-contact-properties-to-api-options.ts:21">
parseContactPropertyToApi coerces an object missing id/object/created_at into ApiContactProperty, so any caller receives an incomplete API payload. Please include the required fields when converting.</violation>
