Removed the 24-column cap from account cells so wide terminals can show full disambiguating labels.
Kept usage bars independently capped and added regression coverage for same-email organization accounts.
Fixes#5701
The /usage show "in use by this session:" marker took only the bare
email from OAuthAccountIdentity, so two same-email Anthropic credentials
in different orgs were indistinguishable. Route the label through a
shared formatActiveAccountLabel that suffixes the active org, matching
the account list and login-success surfaces.
Fixes#5691
renderUsageReports (command-controller) carried the #3268 dedup contract
with no regression test; the PR's added CLI test asserts the opposite
(per-limit CLI rendering shows the note twice). Export renderUsageReports
and add a real regression through it: two accounts sharing one window group
render a provider-wide UsageReport.note once and an identical per-limit note
once. Verified failing on the pre-fix flatMap form (0 and 2 occurrences) and
passing on head (1 and 1).
