Cover what Dokploy v0.30 added

Six new resources, all backed by endpoints that did not exist before v0.30.0
and verified end-to-end against a live v0.30.2 instance:

  dokploy_network         Docker networks, now first-class. Services attach
                          through network_ids, which is what deprecates
                          Compose's isolated_deployment upstream.
  dokploy_dns_provider    Cloudflare or Route53, so adding a domain creates
                          its DNS record.
  dokploy_vault_provider  Env values resolved from HashiCorp Vault, Infisical,
                          AWS, Doppler, Azure or Scaleway at deploy time, so
                          the secret never lands in Dokploy or in state.
  dokploy_schedule        Cron jobs in a container, a stack, or on a server.
  dokploy_volume_backup   Scheduled backups of a named volume — the companion
                          to a mount that persists.
  dokploy_libsql          The sixth managed database engine.

libsql.create is the strictest endpoint in the API: eleven keys required to
be present, several only meaningfully null, no generated service name, and it
returns `true` rather than the row. CreateDefaults and ListIDs absorb all
three so the resource behaves like every other database.

Also filled the gaps a field-by-field diff against the live schema turned up:
domain gains `enabled` (the v0.30.0 park-a-domain toggle), compose gains
create_env_file, icon and service_networks, application gains icon and
preview_require_collaborator_permissions, and mounts accept libsql.

DNS and vault credentials are masked by Dokploy on read, so `config` is
tagged noread and keeps the configured value, as the basic-auth password
already does.
