Implements Task 5. Disables telnet/ftp/www/www-ssl/api/api-ssl (winbox kept
for recovery), sets DNS + NTP client, ensures SSH on the configured port.
Verified run-twice idempotent (changed=0) against crs310-maker on the bench.
Also sets ansible_user=sjat in host_vars for day-2 key auth.

Recorded device facts (CRS310-8G+2S+IN, serial HM40B8TDNDD, RouterOS 7.19.6,
pinned firmware_target 7.19.6). Added encrypted makerfloss-vault admin password
and excluded *.vault.yml from linters. Device bootstrapped over SSH: identity
set to crs310-maker, named user sjat (full) with operator ed25519 key + vaulted
password; key-based login verified from the controller. Default admin still
enabled (hardening + VLANs deferred to the day-2 task files).
