feat: add Offer model and migration

Introduce the Offer model to manage domain purchase offers. The new model includes fields for offered price, messages, intended use, and status with choices for 'pending', 'accepted', and 'rejected', linked to both the Domain and User models. Updated URLs to support offer creation and listing.

This change facilitates better tracking and management of offers made on domains, enabling more robust domain transactions.
