Extracts the swapfile logic out of services/asterisk.sh (previously
DigitalOcean-droplet-gated) into lib/common.sh's ensure_swapfile() —
provider detection was never really the point, the actual condition
that matters is "modest RAM, no swap yet," which applies just as much
to a non-DO VPS running several Docker services at once as it did to a
single-purpose droplet.
- lib/common.sh: new ensure_swapfile(), same fallocate/mkswap/fstab/
swappiness logic as before, threshold raised from 2048MB to 4096MB
(a 4GB box running a full service stack is exactly the case that
motivated this change — the old threshold would have skipped it).
- services/base.sh: calls it unconditionally so every install gets the
same check regardless of which other services get chosen.
- services/asterisk.sh: swapfile call is no longer gated behind
IS_DO — calls the shared helper directly. Kept a standalone-mode
stub (same pattern as this file's other stubbed helpers) so
`sudo bash asterisk.sh` with no base.sh in the picture still gets
it. Idempotent either way: a box that already has swap, or already
got it from base.sh earlier in the same run, no-ops immediately.
