"""CLI lifecycle conturi ROAAUTO (admin gateway).

Onboardeaza/activeaza un client fara INSERT SQL manual, simetric cu
`tools/apikey.py`. Adminul ruleaza pe masina gateway — nicio suprafata HTTP de
admin (admin web vine in 3.3). Optional emite si prima cheie API intr-un pas
(`--with-key`), atomic cu crearea contului.

NOTA: `deactivate` comuta `accounts.active` (lifecycle), dar NU opreste inca
trimiterile — gate-ul worker pe `active` apartine 3.3. Vezi `app/accounts.py`.

Utilizare:
    python -m tools.account create  --name "Service X" [--cui RO123] [--inactive] [--with-key]
    python -m tools.account list    [--pending]
    python -m tools.account activate   --account 2
    python -m tools.account deactivate --account 2
