perf(vegas): report the frame rate when it is worth reporting

Vegas logged an FPS line at INFO every five seconds for the whole of
every run. Measured over two hours on a rig: 1410 samples, 98.5% of them
within 10% of target. The 1.5% that were not included a reading of
8.6fps against a target of 60 -- a real stall, completely invisible
inside 1389 lines reading "59.6". INFO is now reserved for a shortfall,
the recovery from one, and a slow heartbeat so a healthy marquee still
shows a pulse. Scroll-progress tracing drops to DEBUG for the same
reason: it runs for the whole of every scroll and is what you turn debug
on to watch.

Three review findings, all fixed here.

1. Per-frame timing used the wall clock (critical). The loop sleeps the
   remainder of each frame budget:

       frame_elapsed = <now> - frame_started
       time.sleep(max(0.0, frame_interval - frame_elapsed))

   These devices have no RTC, so the clock jumps by however wrong boot
   time was when NTP first syncs. A backward step makes frame_elapsed
   negative, `frame_interval - frame_elapsed` then exceeds the whole
   budget, and the render loop stalls for the size of the correction. A
   forward step instead inflates the p99 and worst-frame figures this
   telemetry exists to report. Both per-frame timestamps are monotonic
   now. start_time stays wall-clock: it is only used for the iteration
   duration report, where a human-readable clock is the point.

2. FPS health state reset every iteration. last_fps_health_log and
   was_degraded were locals of run_iteration(), which is called once per
   cycle. Starting at 0.0 against a monotonic clock, `due` was true on
   the first sample of every iteration, so the 300s heartbeat degenerated
   into one report per cycle -- reintroducing the noise this change is
   about. A recovery that crossed an iteration boundary was never
   reported either, since was_degraded had already gone back to False.
   Both now live on the coordinator and reset in start().

3. The degraded threshold read as an off-by-one. 90% of target is
   deliberate -- a marquee jitters constantly, so "anything below target"
   would report forever and mean nothing -- but nothing said so, leaving
   55fps-against-60 looking like a missed case. The constant now states
   the band and gives that exact example.

Also drops two soccer logo PNGs that a `git add -A` had swept into the
first commit. They are unreferenced, unrelated to frame-rate telemetry,
and 210KB.

Verified: each fix mutation-checked -- restoring the wall clock on either
per-frame timestamp, or making the health state local again, fails the
new tests. 566 passed across the vegas, coordinator and scroll suites.

-SportsUpcoming.update() collected every upcoming game in the schedule window
-and called _fetch_odds() on each one *inside* that collection loop, narrowing
-to upcoming_games_to_show only afterwards. The comment there said odds were
-fetched "only for games that will be displayed", but the sole narrowing it
-applied was show_favorite_teams_only, which is not the default -- so in the
-usual configuration nothing narrowed it at all.
-
-Measured on a live rig: a college league produced 946 upcoming games in one
-cycle and displayed 1 of them. The same shape on the football plugin produced
-a burst of 467 sequential ESPN requests that ran for 35s and blew that
-plugin's 30s update budget, and it repeats every time the 1h odds TTL expires.
-
-SportsLive is deliberately different: it walks the raw event list because it
-has to find which games are live, but only fetches odds for a game that has
-already passed the is_live/is_halftime test, so the fan-out is bounded by how
-many games are actually in progress.
