📝 Description

Dim project cards while status.state is creating/deleting and show a tooltip: in progress, auto-retrying (failed background task), or system sync issue (admin action needed).

🛠️ Changes Made

• useProjectsSyncStatus hook: polls background-task (op_id) + Orca events API every 10s while any project is transitional
• New events-api.js, getBackgroundTask in tasks-api.js
• ProjectCard: dim + tooltip, replaces old session-local delete spinner
• New constants for transitional states / tooltip text / poll interval
• fetchProjects: added silent flag so background polling doesn't show the full-page loader
• Delete flow: refetch project list immediately after delete request (was only refreshing on task completion)
• Mock server: sync test fixtures + events endpoint
