CLI tokens were hardcoded to a 30-day expiry. Make the lifetime
configurable via the CLI_TOKEN_TTL_DAYS env var, with a longer default
of 90 days. The value must be a positive integer number of days; unset
or invalid input falls back to 90. All other token claims are unchanged.
Only affects newly minted tokens — already-issued tokens keep their
original exp.
