fix: harden Vultr create, Gmail identity, and provider retries

Wrap Vultr server creation in DB transactions and delete the remote
instance when local persistence fails (API and Livewire). Scope
plus/dot email normalization to gmail.com/googlemail.com only.
Use throw:false on DigitalOcean/Vultr HTTP retries, and normalize
service log line counts via normalizeLogLines.
