feat(cloud-provider): Add support for Hetzner firewalls, internal networks and backups when creating the Server

[JanThiel]

Changes

Creating a Hetzner Server is straight forward in Coolify. Yet it lacks some essential features of the Hetzner Cloud. Primarily the ability to assign Firewalls, Internal Networks and enable Hetzner Backups at the time of server creation. To do that you have to switch to the Hetzner console afterwards and configure them manually.
This PR introduces these three options to the Coolify Create Hetzner Server Dialog. You can enable backups and select as many pre-existing firewalls and internal networks that are assigned to the Server at Hetzner when creating it.

• AI was NOT used to create this PR
• AI was used (please describe below)

If AI was used:

• Tools used: Codex with GPT-5.4 "High" Reasoning on an OpenAI "Plus" paid account with exclusion of data usage enabled for trainings.
• How extensively:
  • Codex was instructed to add the ability to select and use the Hetzner Firewall + Internal Network via API and
  • to extend the UI based on the existing patterns for the SSH Keys.

All code written by AI was manually reviewed and locally tested using PHPStorm.

Testing

Hetzner:

• Server -> Add -> Hetzner
• Select a valid Token for a Hetzner Cloud Project with a Firewall and Internal Networks present
• Checked for all relevant items being present in the Select in the Coolify UI
• Enable Hetzner Backups
• Select a number of both and verified they were assigned to the new Server and the backups are enabled using the Hetzner Console UI

• Add new API endpoints to fetch Hetzner firewalls and networks for a given Hetzner cloud provider token.
• Expand Hetzner server creation API to accept hetzner_firewall_ids and hetzner_network_ids and forward them to Hetzner.

I am unable to find any relevant existing docs that note any content of the Hetzner specific Create Server Dialog. As it is quite self explainatory and well documented at Hetzner I do not see the need to create additional docs for it.
