Adds Overlay.type='files' whose source-of-truth IS the overlay directory
itself. Users can:
* upload arbitrary files / whole folders by dragging from the OS onto a
folder row in the file tree (one POST per file, queue with
concurrency 3, per-file progress in a floating Uploads panel)
* move via drag-and-drop inside the tree (same gesture, source
distinguishes; refuses cycles)
* create / edit / rename / replace through a single editor modal
(text flavor for editable files, binary flavor with replace-upload
for everything else; filename input is the rename surface)
* mkdir empty folders (slashes allowed for nested intermediates)
* stream a folder as a zip download
* delete files and empty folders
Backend is type-agnostic past the new files_routes endpoints, so the
existing mount / spec / overlayfs / expose_server_cfg pipeline is reused
unchanged. is_editable gates the row's edit affordance and the /save
content rules. Three new safe-resolve helpers (write/delete/move) cover
the new operations with the same anchor-and-resolve pattern as listing
and download. FilesBuilder is a no-op so the build subsystem can
dispatch uniformly.

Adds ScriptBuilder that runs user-authored bash inside the
left4me-script-sandbox helper via run_command, with a 20 GB post-build
disk cap. Registry now {"workshop", "script"}.
finish_job writes Overlay.last_build_status on build_overlay completion.
Drops GlobalMapOverlayBuilder and the now-unreachable
_check_global_overlay_caches in l4d2_facade.

The workshop + managed-global overlay surface fully covers the
admin-SFTP flow that 'external' was a placeholder for. Drop the type
from the model defaults, builder registry, routes, template, and
tests, and add migration 0004 that deletes any leftover external
rows along with their blueprint and job references.

Adds l4d2web/services/overlay_builders.py with a BUILDERS dict mapping
Overlay.type to a builder class. ExternalBuilder is a no-op that just
ensures the overlay directory exists. WorkshopBuilder diff-applies
absolute symlinks under left4dead2/addons/ against the overlay's current
WorkshopItem associations: creates new ones, removes obsolete, leaves
unrelated files alone, and skips uncached items with a warning rather
than producing dangling symlinks.
