feat: add declarative apply & export commands

[nurikk]

Summary

Adds two new commands to the Dokploy CLI for managing resources as code (ref: Dokploy/dokploy#3872, Dokploy/dokploy#4008):

• dokploy apply -f dokploy.yaml — Apply a declarative YAML config to create or update resources on the server
• dokploy export -p <project> -f out.yaml — Export an existing project as a dokploy.yaml config file

These commands enable round-tripping: export a project, check the YAML into git, modify it, and apply changes back.

apply command

dokploy apply -f dokploy.yaml              # Apply changes
dokploy apply -f dokploy.yaml --dry-run    # Preview changes without applying
dokploy apply -f dokploy.yaml --verbose    # Show field-level diffs

• Parses and validates YAML against a Zod schema
• Fetches current server state and diffs against the config
• Creates or updates resources (never deletes — safe by default)
• Name-based matching (project + environment + resource name)
• Two-step creation: create with minimal fields, then update with full config
• Supports all resource types: applications, compose, postgres, mysql, mariadb, mongo, redis, domains, ports, mounts, redirects, security rules, schedules
• Optional serverName field for multi-server deployments
• Env vars managed separately via existing dokploy env push

export command

dokploy export                              # Interactive project selection, stdout
dokploy export -p my-project                # By name, stdout
dokploy export -p my-project -f out.yaml    # Write to file

• Fetches all project resources including child resources (domains, ports, mounts, etc.)
• Strips server-generated fields (IDs, timestamps, status)
• Omits default values for cleaner output
• Resolves serverIds back to serverNames
• Output matches the apply schema exactly (round-trip safe)

New dependencies

• yaml — YAML parsing and serialization
• zod — Schema validation

Test plan

• 32 unit tests passing (schema validation, YAML parsing, diffing, reporting, export transformation)
• Full TypeScript build succeeds
• Both --help commands render correctly
• Manual test: export an existing project, then apply the exported YAML
• Manual test: dry-run against a live server
• Manual test: apply with changes and verify update detection
