Enhance environment configuration and expand Prisma schema for bot management

- Added OWNER_USER_IDS to .env.example for specifying global bot owners.
- Introduced new models in the Prisma schema: CommandOverride, OwnerTeamMember, GlobalUserBlacklist, GuildBlacklist, FeatureFlag, BotPresenceConfig, ChangelogEntry, and OwnerAuditLog to support advanced bot management features.
- Updated env.ts to preprocess OWNER_USER_IDS for better handling of global bot owner IDs.
- Modified ModulePlaceholderPage to ensure proper routing for remaining dashboard modules.
