fix(minimax): track exhausted interval quota (status=2) instead of hi…

…ding it

MiniMax reports current_interval_status=2 when a percentage-based window is
fully consumed (0% remaining = 100% used). minimaxIntervalActive only accepted
status 1, so an exhausted interval was synthesized to zero and dropped - hiding
usage exactly when the user has hit their limit. Treat status 1 and 2 as active
(2 = exhausted); status 3 remains unsubscribed and is dropped.

chore: bump version to 2.11.46

fix(codex): prevent Team workspace token cross-contamination between …

…profiles

shouldUseSystemCredsForProfile only checked account_id when deciding
whether to use system auth.json tokens for a named profile. Team/Business
workspace users share the same account_id, so user B's system tokens
would overwrite user A's profile - causing both profiles to poll with
the same identity and return identical usage data.

Add user_id check: when both the profile and system creds have a known
user_id and they differ, the system creds fallback is rejected.

Verified live with two Team workspace profiles (ecom/ecom1) - after fix,
each profile returns its own usage data independently.
