DGGTweaker Features - Link Hitbox Scaling, RustleSearch button and Lucide Icons

[AlexDavies8]

After Cake mentioned it in the discord I figured I'd port the chat related stuff from my extension to the main chat codebase. Here's a list of the changes:

• Added a new chat setting to increase the clickable area of a link (bigger 'hitbox')
• Added button to the user info right click menu that directly links to rustlesearch.dev
• Basic support for numeric fields in chat settings (in the future could put maxlines in the UI instead of needing a command)
• Icons have been swapped out for Lucide icons to match with the main site redesign
• Button tooltips have been changed from using the title attribute to using tippy, and the tippy style is prettier

I've reverted the link hitbox changes, changed the embed icon and addressed other mentioned changes.
