The web service handles install jobs by fork-exec'ing steamcmd_linux,
a 32-bit binary. With SystemCallArchitectures=native (x86_64 only) the
kernel SIGSYS-kills it on its first i386 syscall — surfaced as bash
exit 159 (= 128 + SIGSYS) in job logs. Mirror the server drop-in's
`native x86` so the install path works again; the server unit already
needed the same allowance for srcds_linux.

Hardening directives leave the base unit body and live in:
deploy/files/etc/systemd/system/left4me-web.service.d/10-hardening.conf
deploy/files/etc/systemd/system/left4me-server@.service.d/10-hardening.conf
Reference units now describe just the base operational shape (exec,
env, restart, resources). Tests split: base-unit content and hardening
profile are asserted separately.

step 2. ckn-bw lands the matching reactor surgery + symlink delivery.
