Adds the #471 "secure" steps as opt-in flags on `setup enable-ssh`, off by
default (per the decision that closing 17000 must be opt-in):
- --close-17000: blocks port 17000 from the LAN. Manager.Close17000 remounts /
read-write, persists an idempotent iptables rule in
/etc/init.d/Firewalls/update_iptables (keyed on a marker), and applies it
immediately; loopback access is kept.
- --authorized-key <pubkey>: Manager.InstallAuthorizedKey writes the key to
/home/root/.ssh/authorized_keys so root SSH no longer relies on the
empty-password login.
Both run over the SSH the enable step just opened. Default output reminds the
user that 17000 is left open and how to close it. Unit tests cover the
firewall command sequence and the key upload path.

Adds `soundtouch-cli setup enable-ssh`, the first iteration of foob61451's #471:
turn on SSH on a speaker that has no prior SSH access and without a USB
recovery stick, then fall into the migration / CA-install flow we already have.
Mechanism (new Manager methods, reusing the existing telnet :17000 client):
- EnableSSHViaTelnet sends `envswitch boseurls set "<url>;touch
/tmp/remote_services;/etc/init.d/sshd start" "<url>/update"`. The injected
shell commands run when the speaker next parses its boseurls (~60s), starting
sshd. The URL is only the vehicle for the injection — it does NOT need a live
server, so this works before any AfterTouch service exists.
- WaitForSSHPort polls :22 until sshd is up.
- ResetBoseURLs restores a clean marge URL afterwards.
- Persistence reuses the existing EnsureRemoteServices (writes the marker over
the now-open SSH so it survives reboot).
CLI flow: inject → wait for :22 → reset clean URLs → persist. `--service-url`
is optional (placeholder used otherwise; set real URLs later via migration).
Securing/closing port 17000 is deliberately OPT-IN and not done here. Unit
tests pin the exact injected/reset command strings and the double-quote guard.
This lands in -cli first (cheapest to iterate); the future soundtouch-app can
reuse the same Manager methods.
