Deletes the global_map_sources, global_overlay_refresh, global_map_cache,
and global_overlays service modules and their tests. Removes the
refresh-global-overlays CLI command, the /admin/global-overlays/refresh
route, and the GlobalOverlaySource view in overlay_detail rendering.
Drops py7zr from dependencies — was only used by the deleted subsystem.
The job_worker scheduler still tracks refresh_global_overlays; that
cleanup is Task 4. Deploy/README references are Task 8.

Adds two managed system overlays (l4d2center-maps, cedapug-maps) that
fetch curated map archives from upstream sources and reconcile addons
symlinks for non-Steam maps. A daily systemd timer enqueues a coalesced
refresh_global_overlays worker job; downloads, extraction, and rebuilds
run in the existing job worker and surface in the job log UI.
Schema: GlobalOverlaySource / GlobalOverlayItem / GlobalOverlayItemFile
plus nullable Job.user_id so system jobs render as "system" in the UI.
The new builder reconciles symlinks against the per-source vpk cache
and leaves foreign symlinks untouched. Initialize-time guard refuses
to mount a partial overlay if any expected vpk is missing from cache.
Refresh service uses shutil.move to handle EXDEV when /tmp and the
cache live on different filesystems.

Adds l4d2web/services/steam_workshop.py: parse_workshop_input (single ID,
URL, or multi-line batch), resolve_collection (HTTPS POST to
GetCollectionDetails), fetch_metadata_batch (HTTPS POST to
GetPublishedFileDetails with consumer_app_id == 550 enforcement that
raises WorkshopValidationError in add-mode and silently skips in
refresh-mode), download_to_cache (atomic + idempotent on mtime+size),
and refresh_all (ThreadPoolExecutor with per-item error collection).
Adds requests as an explicit dependency.
