Backend: add POST /docker/containers/stats and DockerService.get_containers_stats to fetch resource metrics for multiple containers in a single docker stats call (parses JSON lines and returns a map keyed by ID/Name). Validates input and logs errors.
Frontend: refactor Docker page into a two-column workspace with a left sidebar for targets, resources and maintenance, and a main area with workbar and panel. Add support for multiple targets (default local), fetch available servers, and expose selection UI. Implement bulk stats fetching via api.getContainersStats for local hosts, periodic refresh, per-container stats caching, sorting controls for the container list (status/name/image/cpu/memory/created), and improvements to the container inspector (drawer behavior, loading timer, close action). Update API client with getContainersStats and adjust container stats parsing to handle multiple shapes.
Styles: add comprehensive SCSS for the new workspace, sidebar, inspector drawer, inventory and sort control, and responsive behavior.
Add backend support for listing Docker Compose projects: new /docker/compose/list endpoint and DockerService.compose_list with a JSON-parsing path and a fallback that builds projects from container labels for older compose binaries. Fix RemoteDockerService to use DockerService.get_container for remote/local inspection. Large frontend updates: DashboardLayout supports full-page routes; Databases page received a visual refresh with engine status badges and a summary grid; Docker page refactored extensively — normalize container fields, consistent ID/name/image helpers, table-based resource list, inspector sidebar (ports/mounts/env), resource bars, improved logs/exec handling, and disabled actions for remote targets. Compose tab now uses the new compose list API and streamlines compose actions. File Manager now keeps current path in the URL (search params), tracks previous target changes, and manages selection state more robustly. Miscellaneous UX fixes and icon updates across pages.
Broad refactor and hardening across backend and frontend:
- Standardize API error responses by removing legacy `success` flags and returning concise error payloads.
- Replace inline admin decorators with centralized middleware import (admin_required) in DB and Docker APIs.
- DatabaseService: add safer MySQL execution helpers and secure user-creation flow (hex-encoding, env-pwd usage) and improve pg drop to validate identifiers.
- Models: add eager-loading (subquery) for relationships and add indexes to frequently queried columns to reduce N+1 and improve performance.
- DockerService: add structured logging and error messages for better observability when Docker commands fail.
- Config: tighten ProductionConfig cookie settings (secure, httponly, samesite).
- Frontend: migrate many .less styles to .scss, add new security UI components and API client modules, update package metadata accordingly.
- Misc: add APP_IMPROVEMENTS.md to .gitignore.
These changes improve security, reliability, observability, and frontend styling consistency.
