The timers used to delete everything an account kept, unsent mail included.
They now follow the refused-login rule: sign out and hide, the next sign-in
brings it back, otherwise it goes after 30 days. A login without "Remember
me" that ends with the browser, an admin wipe and a wipe from settings don't
change.
- `wipeOnRefusedLogin` is now `wipeOnForcedSignOut`, since it also covers the
limits. The server's `SESSION_TOO_OLD` goes the same way, as `session`.
- A refused account beside one that stays signed in shows in the switcher as
needing sign-in, with the count and the date, and gets one toast.
Existing tests changed because the rule did: the session timer tests expected
a plain `logoutAll`, and the auth store tests expected no hook at the session
limit.
Input inside an iframe never reaches the host window, so the idle timeout
signed users out while they worked in a plugin page, dialog or panel. The
sandbox runtime now reports trusted input in its frame (the guard's own
events, focus left out) through a MessagePort it hands the host with
sandbox-ready, before any plugin code runs, at most once per 15 s. The
host bridge passes it to a small notifier the session timeout guard
counts like its own window's input, so it reaches the other tabs too.
