Resolve conflicts between main's security fixes and v4.5 features:
- Keep v4.5 features (log redaction, multi-S3 backups, transfer flow,
scheduled task modal, sidebar) and port main's fixes into them.
- Reuse RequiresDeployAbility for the Hostinger create endpoint.
- Align MCP tool abilities and descriptions with main's new deploy
requirements, and use deploy tokens in the affected MCP tests.
- Drop the duplicate DockerCleanupJobTest helper and tests, and the
exportBundle test for a method v4.5 removed.
