feat(gitea): add optional internal URL for Gitea integration

- Introduced a new field `giteaInternalUrl` in the Gitea provider settings to allow users to specify an internal URL for OAuth token exchange when Gitea runs on the same instance as Dokploy.
- Updated the Gitea provider forms to include the new field with appropriate descriptions.
- Modified the token exchange logic to utilize the internal URL if provided, enhancing connectivity options for users.
- Updated database schema to accommodate the new field.
