Fix updates page translation errors and data fetching

- Fix translation interpolation format from double to single curly braces for next-intl
- Create API route handlers for characters, weapons, summons, and raids
- Fix infinite recursion in ChangelogUnit by renaming fetch function to fetchItem
- Simplify fetch logic and add proper dependencies to useEffect
- Fix activeYear defaulting to 2024 instead of current year (2025)
