[Feat] Gitea/GitLab Custom SSH Ports

[RichardAnderson]

This pull request introduces support for configuring a custom SSH port for Gitea and GitLab source control providers, allowing users to specify which port should be used when cloning repositories. It also generalizes provider editability, so only safe, whitelisted fields can be edited, and ensures the UI and API reflect these changes. The most significant changes are grouped below.

Gitlab UI

Gitea UI

Backend: SSH Port Support and Provider Editability

• Added ssh_port as a configurable and editable field for Gitea and GitLab providers, including validation, normalization, and persistence logic in their respective provider classes (Gitea.php, Gitlab.php). The default is 22, but users can specify a different port if needed.
• Updated the abstract provider and interface to require implementation of getSshPort, editableFields, editRules, and editData methods, ensuring only whitelisted fields can be edited and preventing unsafe mass assignment.
• The edit action now merges provider-specific rules and data handling, so only allowed fields are validated and saved.

UI/API: Dynamic Edit Forms and Schema Updates

• The API resource and OpenAPI schema now conditionally include the ssh_port field for providers that support it, with proper typing and documentation.
• The frontend edit form dynamically renders only the editable fields for each provider, using provider config and dynamic field components, ensuring the UI matches backend validation and security.
• Registration and configuration of providers now include a list of editable fields, so the UI and backend remain in sync about what can be edited.

Operational: SSH Clone Script and Usage

• The SSH clone script and logic now use the configured port when cloning repositories, and update ssh-keyscan and SSH config generation accordingly.

Provider Registration

• When registering Gitea and GitLab providers, the SSH port field is included in their dynamic forms, with defaults and descriptions.

These changes make SSH port configuration safer, more flexible, and more user-friendly for self-hosted source control integrations.

Resolves #1085

Pull request overview

This PR adds configurable SSH clone ports for Gitea and GitLab source control providers and threads that configuration through backend provider data, clone script rendering, API resources, and the edit UI.

Changes:

• Adds provider-level SSH port validation, normalization, persistence, and clone-time usage.
• Introduces editable provider fields so the UI only renders whitelisted source-control settings.
• Updates TypeScript/OpenAPI schemas and feature tests for SSH port behavior.
