feat(applications): job application tracker with AI copilot

Add an Applications module at /dashboard/applications: pipeline board
(dnd-kit), table view with bulk actions, Insights (fit tiles, funnel,
sources, shareable funnel-flow SVG), campaigns, tags, CSV import, and
Add/Edit/Detail slide-overs. Each application links a live Reactive
Resume.

AI "Application Copilot" (applications.ai.*): job-posting autofill,
resume↔job match score (fit ring), resume tailoring, and cover-letter /
follow-up drafting — via the user's configured provider.

Board cards + table rows get context menus (edit / move / archive /
delete). Charts are CSS/SVG (no new chart dep); adds a UI Checkbox.

Also includes local TanStack devtools setup and toolchain bumps.
