fix(discord): restrict activity types and statuses to valid enum values

- Removed 'offline' from valid config statuses (use 'invisible').
- Restricted activityType to 0, 1, 2, 3, 5 (excluding custom/4).
- Added logic to only send 'url' when activityType is 1 (Streaming).
- Updated Typescript definitions and Zod schemas to match.
