feat(application): add scaling and rollout controls

[cromulus]

Summary

• add a first-order "Scaling & Rollouts" card to application general settings
• expose instances and deployment strategy without requiring users to edit raw swarm rollout settings
• warn when zero-downtime rollouts are configured without a health check or with host-published ports that can still conflict

Notes

• this is scoped to Dokploy applications only as a first pass
• saving normalizes custom swarm mode back to simple replicated scaling for this UI path
• health-check authoring still lives in Advanced -> Cluster Settings; a dedicated first-order health-check UI can follow separately

Validation

• biome check apps/dokploy/components/dashboard/application/general/show.tsx apps/dokploy/components/dashboard/application/general/show-scaling-and-rollouts.tsx apps/dokploy/components/dashboard/application/general/scaling-and-rollouts.ts apps/dokploy/__test__/application/scaling-and-rollouts.test.ts
• pnpm --filter=dokploy exec vitest run --config __test__/vitest.config.ts __test__/application/scaling-and-rollouts.test.ts
• git diff --check origin/canary...HEAD
