feat: rename labymod -> labyclient & bump minecraft pinger version

[Flash303]

This pull request primarily standardizes the naming of "LabyMod" to "LabyClient" across the codebase and updates a backend dependency. The changes ensure consistent branding and improve clarity for users in all supported languages, while also making a minor backend improvement for type safety and dependency freshness.

Branding and Localization Updates:

• Renamed all user-facing references from "LabyMod" to "LabyClient" in the English, German, Spanish, French, Italian, Japanese, Korean, and Dutch locale files, including sidebar text, partner labels, and informational sections. This ensures consistent branding throughout the UI. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24]
• Updated documentation and code comments to use "LabyClient" instead of "LabyMod" for clarity and accuracy. [1] [2]

Backend Improvements:

• Upgraded the minecraft-pinger dependency from version 0.1.6 to 0.1.8 for the backend, ensuring the latest features and bug fixes are included.
• Improved type safety in the mojang_checker_worker by explicitly typing consecutive_failures as u32 and converting REQUIRED_FAILURES to u32 for comparison. [1] [2]
