Favorites and Pins: pin projects in the sidebar

[TheSethRose]

Summary

Allow pinning projects to the sidebar for quick access.

Current behavior

• Projects are listed only on the Projects page (src/app/(dashboard)/projects/projects-client.tsx).
• Sidebar navigation is static in src/components/dashboard/Sidebar.tsx.

Target behavior

• Add pinned projects section in the sidebar.
• Pin/unpin control on project cards or project detail page.
• Persist pins across sessions (DB-backed or localStorage).

Scope

• UI affordance to pin/unpin projects.
• Storage for pinned project IDs.
• Sidebar rendering of pinned projects.

Acceptance criteria

• Users can pin/unpin a project from the UI.
• Pinned projects appear in the sidebar with quick navigation.
• Pins persist across reloads.

Open questions

• Persist pins per user in DB vs. localStorage?
• Limit number of pins?
