UX-54 round 3: tomorrow's blocks last as long as control acts, give blocks checked at run start

- Tomorrow's grid block is drawn to where control stops charging. A cheap run
  is sized for all batteries together; a slower one is still below
  `charge_to()` when it ends and control plans the next cheap slots. The tab
  asks `modetrade.energy()` and `priceruns.plan()` with the packs at the
  curve's level and extends the run, so the curve charges as long.
- Each battery's block ends where it is at its own level (grid) or at the
  floor (give). The curve puts a point where a battery reaches its charge
  level inside a step.
- `homeview.mode_runs(ahead=f, rp=...)` reads each block at the level the
  curve has when it starts, with Home's own filter and MIN_KWH: no give block
  at the floor, no grid block at the planned level. Home never passes either.
- `no_tomorrow` names the hour from `solarfc.BELL_FROM_H`, where the curve
  stops.
- test_ux54.py part 7 compares control (`_mode_roles()` every 15 minutes) with
  the tab with no tolerance, and adds the cloudy / floor case.

No decision, command, timing or option key changes.
