perf(search): narrow the recency window 90d -> 60d

Operator request. Bigger effect than expected.

THREE constants, not one

"90" appeared in three places, and two of them are load-bearing:

  universal-search-service.ts   UNIVERSAL_SEARCH_WINDOW_DAYS  orders scope
  quotes-search-service.ts      SEARCH_RECENT_WINDOW_DAYS     quotes pushdown
  quotes-service.ts             SEARCH_RECENT_WINDOW_DAYS     exported; shared
                                with the /quotes page + archive

The last two must stay equal — the /quotes page renders "Show recent
(last N days)" from the exported constant while the server filters on
the private one, so moving them apart desyncs the label from the
behaviour with no error anywhere. All three moved together. Universal
search calls searchQuotes without `includeOlder`, so it inherits the
quotes window; changing only the universal constant would have left
global search reading 60 days of orders and 90 days of quotes behind a
single "last 60 days" label.

The UI label reads windowDays straight off the service, so it follows.

MEASURED

Order candidate set collapses — the window was carrying far more than
the linear slice it looks like:

  90d -> 5,394 orders / 16,640 items / 6,696ms scope scan
  60d ->   972 orders /  3,307 items / 1,606ms scope scan

Cold search "tiaan": 17-22s -> 4.6s measured. That is most of the
mitigation the TTL bump was papering over, so the long-deferred pushdown
rewrite is now worth less than it was this morning.

Quotes genuinely drop, and it is real rather than a regression: Tiaan's
own quotes go 22 -> 6 between a 90- and 60-day window, because that
band is where most of his quotes sit. Verified against PB directly.

ALSO

Pinned the clock in the age-chip test. It asserted "4d" against a
fixture dated four days before the wall clock, so it expired the day
the date rolled past — it failed on this run for exactly that reason.
