v0.2.4 — Name Cards, Flat Design, and Admin Password Reset

This release introduces a new name card print mode, a refreshed flat visual design, and several quality-of-life improvements across the application.

Key improvements

• Name card printing — A new "Names" print mode generates large-format name cards for bins, with configurable font size, layout options, and PDF export. Great for labeling shelves and storage areas at a glance.
• Flat design refresh — Reduced blur, shadows, and rounded corners across the entire interface for a cleaner, more readable look. New heading font and semantic color tokens improve visual hierarchy.
• Admin password reset — Location admins can now generate a one-time password reset link for any member directly from the members dialog.
• Large item list handling — Bins with many items now show a collapsible list with inline search, making it easier to find specific items without scrolling.
• Item sorting — Sort items within a bin by name, quantity, or date added.
• Health endpoint — New GET /api/health endpoint with database connectivity check, useful for Docker health checks and monitoring.
• Hardened security — Stricter security headers and cookie policy for self-hosted deployments behind reverse proxies.
• iOS print fix — Short codes now center correctly under QR codes in Safari print preview.
• New documentation — Added reverse proxy setup guide, backup/restore guide, and updated all existing docs to reflect recent features.
