Config-UI / Images & Icons Cleanup

This PR updates images and icon usage on Config-UI to resolve conflicts with licensing requirements. These changes will also need to be cherry-picked to main branch after merge.

• Remove unused PNG/SVG Image assets
• Remove Headline Icons
• Replace main Provider Brand Logos (provided by Product & Design Team)
• Use generic icon for ae, dbt, gitextractor and refdiff plugins
• Cleanup Imports

Developer notes on remaining assets in config-ui/images:

help.svg // Help Icon Exported from Blueprint JS Icons (Apache 2.0 licensed)
logo.svg // Merico Logo Asset (licensed for devlake?)
slack-mark-monochrome-black.svg // Slack Brand Logomark

Hi @e2corporation @mindlesscloud @klesh @yumengwang03 @WillemJiang , I've checked all following images in Grafana. They're all created by Wenfeng Piao, our designer. So I think the images listed below are fine.
As for the image 'img/wechat_community_barcode.png', I think it's the barcode for our Wechat community, which was generated by WeChat, so I think it's also OK legal-wise.
