Replace the single `switch_admin_user` day-2 task with a `switch_operators`
list in host_vars: one RouterOS user per person, each with the public keys
that may log in as it. Logins become attributable and revocable per person
instead of accreting as extra keys on `sjat`.
Adds claus@stjerno.dk as user `claus` (group full), and codifies the two
keys already on the device (sjat's mamba seat, the claude@ubongo automation
seat that was hand-imported earlier today).
Two things the mechanism has to get right:
- Idempotency: query /user/ssh-keys first and upload only missing keys.
An unconditional net_put reports changed on every run.
- No passwordless accounts: WinBox/console accept an empty password and
WinBox is deliberately left on for recovery, so each operator gets a
vaulted password. users.yml asserts one exists before touching anything.
Verified: yamllint, ansible-lint (production), syntax-check, and the play
run twice against crs310-maker — second run changed=0.

Implements Task 6. Guards user creation with :if [find]; disables the built-in
admin (switch_disable_default_admin) now that sjat key login is proven. Verified
run-twice idempotent (changed=0); admin disabled=true, sjat reachable on bench.
