* feat(dashboard): dismissible system notice banner for every signed-in user
Operator-set banner ("high load right now, some pages may respond slowly
or fail") rendered under the dashboard chrome for every signed-in user
while NEXT_PUBLIC_SYSTEM_NOTICE_UNTIL (ISO timestamp with offset) is in
the future. Closing it stores the deadline in localStorage, so each
browser sees it once; the banner hides itself at the deadline in open
tabs and is not rendered at all after it.
Why the problem occurred: there was no way to tell every user something
about the system itself. The existing banners are all per-company state
(sandbox, seat grace), so an operator notice had no home.
What was removed or simplified instead: no notices table, no migration,
no admin UI. One public env var carries both the on/off switch and the
expiry, and the same value is the dismiss key, so a later notice re-shows
once without any code change. No DB read, which matters because the
first use is a DB restart window.
Why this over the proposed shape: the request was a banner "until 23:00
tonight". Hardcoding that in code would need a second PR to switch off
or reuse; a DB-backed notice would read the database that is about to
go down. The env var expires on its own, and unset means gone.
Fixes #2463

* fix(dashboard): system notice survives long deadlines, blocked storage, and every layout shell
Skeptic findings on 839a255f3:
- setTimeout clamps delays above 2^31-1 ms to ~1 ms, so a deadline more
than 24.8 days out hid the banner instantly. Wait in bounded steps and
re-check the clock.
- window.localStorage is a throwing property access when a browser blocks
site data; read it behind a try so the dashboard never crashes over a
notice.
- The close button was a hand-rolled 22px icon button; design.md requires
the shadcn icon Button (40px target).
- The byrå-consultant shell and the stale-cookie shell rendered no banner,
so "every signed-in user" was not true. The banner is now computed once,
before the shell branches, and mounted in all three.

* fix(dashboard): system notice deadline requires a UTC offset
A date-time without Z or a numeric offset parses as local time, which is
UTC on Vercel and the operator's zone locally, so the same value would
mean different instants. Reject it instead (CodeRabbit on #2464).
Declined: scoping the dismissal key by user id. The notice is about the
system, not the account; per-browser dismissal is the sandbox banner's
semantics and keeps identity out of layout chrome.
