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.

- Native <dialog> modal infra (CSS + ~30 LOC JS, no framework) used for
create forms and delete confirmations.
- Index pages become listing-only: + Create button opens a modal; the
broken blueprint Actions column and inline overlay edit cells are gone.
- Server detail gains a blueprint reassignment form; existing Delete
button now opens a confirmation modal before tearing down the runtime.
- Blueprint detail gains a Delete button + confirmation modal (was
unreachable from the UI before).
- New overlay detail page at /overlays/<id> with edit form, "Used by"
blueprints list, and delete (admin only).
- Server create: port field is now optional; backend auto-assigns the
next free port from LEFT4ME_PORT_RANGE_START/_END (default
27015-27115). 409 on range exhaustion.
- New routes: POST /blueprints/<id>/delete (form sentinel matching
overlays pattern), POST /servers/<id> (form-friendly blueprint
reassign), GET /overlays/<id>.
- Server delete operation now redirects to /servers; overlay update
redirects to /overlays/<id>.
Server rename remains unsupported pending an id-vs-name design pass for
l4d2host (the runtime directory is name-keyed; renaming would orphan
files).
