refactor(interaction): separate view and update logic into modular files

- Extract slug editing logic to slug.go (slugView/slugUpdate)
- Extract commands menu logic to commands.go (commandsView/commandsUpdate)
- Extract coming soon modal to coming_soon.go (comingSoonView/comingSoonUpdate)
- Extract main dashboard logic to dashboard.go (dashboardView/dashboardUpdate)
- Create model.go for shared model struct and helper functions
- Replace math/rand with crypto/rand for random subdomain generation
- Remove legacy TLS cipher suite configuration
