fix: add validation and escaping for Docker network names

Browse Source 
Add strict validation for Docker network names using a regex pattern
that matches Docker's naming rules (alphanumeric start, followed by
alphanumeric, dots, hyphens, underscores).

Changes:
- Add DOCKER_NETWORK_PATTERN to ValidationPatterns with helper methods
- Validate network field in Destination creation and update Livewire components
- Add setNetworkAttribute mutator on StandaloneDocker and SwarmDocker models
- Apply escapeshellarg() to all network field usages in shell commands across
  ApplicationDeploymentJob, DatabaseBackupJob, StartService, Init command,
  proxy helpers, and Destination/Show
- Add comprehensive tests for pattern validation and model mutator
