bw's name search is fuzzy: every agent email contains "coo"
(tsgstaff-coo-*), so `bw get totp "coo Cloudron"` matched 10 items and
errored. get_totp now resolves via get_item_id (exact-name filter)
first, mirroring get_item_password.
Added validate-all-logins.py: per-agent fresh-browser-context login
(shared contexts carry session cookies and hide the login form),
asserts password+TOTP round-trip, then verifies every stored API
credential against its system. First full run: 9/10 PASS.
Known failure: vp-compliance stored password does not match the
account ("Incorrect username or password" pre-TOTP) -- enrollment
typed a different value than stored. Needs Cloudron admin reset,
then update_item and re-validate.
