Adds a /servers/<id>/files/download route mirroring the overlay download
endpoint. Same safety rules: real-path must resolve under LEFT4ME_ROOT
(merged view threads through `installation/` and overlay layers, all
already inside the root). The server file-tree partial now renders
download links.

Adds a Files section at the bottom of the server detail page that lists
the kernel-overlayfs merged view at runtime/<server_id>/merged/. Reuses
the overlay file-tree partial via two new template variables:
- files_base_url: parent passes "/overlays/<id>" or "/servers/<id>"
- download_supported: false for servers (runtime holds large game
binaries; no download endpoint), true for overlays (existing behavior)
New service helper safe_resolve_for_server_listing() rejects path
traversal beyond the merged root and returns None when the overlayfs
mount doesn't exist (server never started or just reset).
New route GET /servers/<id>/files?path=<rel> returns the lazy-load
file-tree fragment, gated to the server owner. No download counterpart.

Adds a server-rendered collapsible file tree section to the overlay
detail page so users can verify what their script/workshop overlays
produced and pull individual artifacts (VPKs, configs) without SSH.
HTMX-driven lazy folder expansion with click-to-download via send_file;
symlinks land anywhere under LEFT4ME_ROOT (so workshop addons stream
from the shared cache) but escapes are refused. Same access rule as the
rest of the page (admin or owner). 39 new tests; full web suite green.
