fix(ui): wrap destination list to prevent overflow on small screens

[mklozinski]

Changes

• Destination buttons (from "Available Destinations" in "Destinations" tab on server page) overflow the container on narrow screens, and long network names break across multiple lines inside the buttons (browser wraps at hyphens)
• Added flex-wrap to container + min-w-fit to items, same pattern "Found Destinations" section already uses in same file

Issues

• None — small UI fix per contributing guidelines.

• AI was used (please describe below)

If AI was used:

• Tools used: Claude Code for VS Code (Fable 5)
• How extensively: I found the fix myself in Devtools, AI helped locate the file and existing patterns.

Testing

• Tested with a local development instance (docker compose dev setup from DEVELOPMENT.md, seeded, added destinations).
  destination buttons wrap into rows at narrow widths, no overflow, no mid-word breaks. "After" screenshot above is from this instance.
• Additionally verified on a live v4.1.2 instance by applying the same patch inside the running container (view cache cleared, then reverted).
