Add per-player menu localization and refactor menus

Introduces per-player localization for menu categories and items using translation keys and IStringLocalizer, allowing modules and the main plugin to display menu names in the player's language. Refactors menu registration and builder logic to use translation keys, updates API and documentation, and adds database provider upsert query abstraction for player IPs. Also updates version to 1.7.8-beta-4 and corrects a translation string typo.
