fix(discord-gateway): add missing dependencies (axios, ws, @types/pg, @types/ws)

After removing root package deps, discord-gateway service was missing:
- axios (used in indonesianTextNormalizer.ts)
- ws (used in broadcaster.ts)
- @types/pg (needed for TypeScript pg declarations)
- @types/ws (needed for ws types)
