Add Advanced Filters to the Warmane Trade System

Current Issue:
When browsing for characters, especially within a specific budget range (e.g., 100–200 coins), the current trade system lists a large number of results, many of which are not relevant. For example, searching for a Shaman shows dozens of characters, but the vast majority do not meet my desired criteria. This makes it time-consuming and tedious to check each listing individually to find one that matches my needs.

Proposed Solution:
Introduce advanced filtering options in the Trade system. These filters could allow players to search for characters based on specific:

Items (e.g., GTS, Terenas, etc.)

Mounts (e.g., Razzashi Raptor)

Achievements (e.g., Herald of the Titans)

Currencies (e.g., more than 100 Emblems of Frost)

Such filters would significantly improve the usability of the Trade system, save players time, and make it easier to find characters that truly match their preferences. Implementation should be straightforward, as it mainly involves adding additional search parameters to the existing system.
