Introduce a tabbed repository modal with new styling and grouped lists. Adds CSS for modal tabs and repo-owner group/divider visuals. In JS, add activeReposTab state, helper functions to infer repo owners and match remotes, and utilities to group server and local repos. Replace flat lists with serverRepoListTemplate/recentLocalReposTemplate and group local scan results; update reposModalContent to render tabbed local/server panels and bind tab click events.
