Pimp My Bot - Themes Feature

[justncodes]

Summary

Introduces a new theming system (also known as "Pimp My Bot") that allows admins to fully customize the visual appearance of the bot's messaging including emojis, colors, and dividers.

This PR is a continuation of the work done in #69 with credit to @G0DeSs76 and @bahraini69 for their work on the idea and code and @zenpaiang for reviewing.

I'm submitting this PR for review and testing. The functionality is ready, but there may still be some issues to iron out.

Key Features

Theme Management

• Create, edit, import/export and delete custom themes
• Import/export themes as JSON for sharing between servers
• Per-server theme activation (each server can use a different theme)
• Server-scoped ownership: server admins can only edit/delete themes created on their server

Customization Options

• 70+ customizable icons (supports Unicode emoji, custom Discord emoji, and image URLs)
• Various embed colors for different message types and 3 configurable dividers (upper, middle, lower)
• Live preview system showing how themes appear in real bot embeds

Yay, I'm so excited!

Working on building a web portal for sharing themes but it's not ready yet, so I have disabled the Share option for now. Will be ready by the time of publishing the next bot version. Otherwise the themes cog is now ready, so I will merge it in to main.
