feat: add mobile project editor with worktree reorder and delete

Replace the up/down arrows in the mobile project reorder list (drag already
covers reordering) with an edit button that opens a dedicated project editor
surface: rename, pick icon and color, and discover a favicon (no upload).

The editor lists the project's worktrees with drag-to-reorder (persisted per
project, like project order) and a delete button that opens a mobile
confirmation built on the shared worktree primitives — archiving attached
sessions and optionally removing the local/remote branch.
