fix: Add safe parsing for weapons and chat API endpoints

- Use parseMatchWeaponsSafe instead of parseMatchWeapons
- Use parseMatchChatSafe instead of parseMatchChat
- Throw clear error message when demo not parsed yet
- Prevents Zod validation errors from reaching page loaders
- Matches the pattern already used for rounds endpoint

This fixes Zod errors when navigating to match detail pages where
the demo hasn't been fully parsed yet by the backend.
