Coolify v4.3.15 release notes

Added per-domain internal port overrides for applications, Docker Compose services, and preview deployments across Traefik and Caddy. Public domain URLs remained portless, while the UI showed effective ports and warned about unrecognized ports. (#11594)
Consolidated service database, volume, and directory backups into one page with schedule editing, on-demand runs, combined history, live status, downloads, and imports. (#11574)
Added domain management and DNS status checks for preview deployments.

Blocked read-only team members from directly invoking protected Livewire mutations for credentials, servers, applications, databases, and security resources. (#11596)
Preserved every application domain in COOLIFY_URL and COOLIFY_FQDN, including multi-domain configurations with ports. (#11527, fixes #10824)
Kept stopped containers visible after they reached their restart limit, prevented further automatic restarts, and added retry deployment and container removal actions. (#11566, closes #10624, #10906, and #11521)
Rejected invalid build-time environment variable names before builds started and reported the offending key with rename guidance. (#11575)
Prevented unauthorized users from receiving stored private keys and GitHub App secrets in Livewire state.
Restricted web terminal SSH commands to approved hosts, keys, ports, and options.
Preserved existing domains when switching an application to Docker Compose and waited for confirmation before loading its Compose file.
Redirected immediately after resource deletion while cleanup continued after the response.

Improved the Docker Compose editor layout on mobile screens.
Warned before removing a port required by a service domain.
Warned that full PostgreSQL restores could overwrite administrator passwords.
Reduced the remotely callable Livewire API and kept authorization checks on user-facing write actions. (#11578)
