Marc-André Bombeck 0e991c3640 fix(measurements): fold a dense pulse stream inside the 90-day raw window ...

Past 90 days every pulse reader already folded in SQL. Inside it, three
still read every raw heart-rate row, which on a watch that records a
reading a minute is 130 000 rows per read (#1023):

- The insights page's resting-pulse proxy, used when an account has no
  resting heart rate, walked the whole window to take one percentile per
  day and held the event loop for over a second per view. It now folds in
  Postgres (`readRestingPulseProxy`) with the same percentile, rounding,
  minimum-sample rule and day anchor.
- The per-kind series sent every reading: 14.7 MB for 90 days. A pulse
  window with more than 10 000 readings is now bucketed per local hour,
  mean plus low/high band, with stats still over the readings.
- The doctor report drew every reading into one sparkline. A pulse window
  over the same cap now takes the per-day path longer reports already use.

Sparse pulse (a cuff, hourly imports, a watch sampling every few minutes)
stays under the cap and keeps its raw shape.
