feat(seer): new copilot integration

[sehr-m]

Currently GitHub Copilot coding agent handoff is a permission set at the user-level as users must choose to connect their github account. However, after some discussion we think copilot integration should have to be allowed at the organization admin in line with how cursor and claude operate. Since copilot does not need an api key or any credentials, this PR creates a DirectEnableIntegration which skips the pop up stage and enables the integration. Only if this is enabled are users within the org provided access to "Setup/Send to GitHub Copilot" option for the handoff dropdown.

This is an intermediate fix for now. There are several changes planned for coding integration settings that would likely make this unnecessary. Additionally, we only launched EA of copilot in the last couple of weeks, this should not be merged or put out until we decide how we would like to inform our current users that this will break their setup (minimally).
