Draw the game's status icons and fill gauges on the board

[OGMods]

What this adds

Each building on the board now shows the same overlays the game draws, using the game's own art pulled from its files:

• State icon, following the game's own status definitions (its Status_*_Desc text):
  • red triangle: offline, nothing it can work with is adjacent (e.g. a generator with no heat source beside it)
  • zzz: idle, partners are adjacent but don't need it
  • warning thermometer: overheated, waste heat isn't covered, so it shuts down
  • gauge: wasting heat, a generator at full capacity beside a reactor with more than 10% of its heat unused
  • nothing over a building that's working
• Anomaly icon at the building's foot: Singularity's boosted/downgraded icons, Tidal's wave, Cryo's cooler icon. It appears only where the scorer rated that building above or below its plain tier, so it marks exactly the buildings the anomaly affected.
• Fill gauge ("70%"): how hard the building is working, measured against the same ceiling the readout prints, so the two always agree. It sits on a see-through pill with the game's dial icon and can be turned off in Settings → Building gauges.

Icon positions and sizes come from the game's building template. The icons ship as files in public/icons/ and the extractor regenerates them.

How it's built

• ratedPlacements rates the whole board in one pass; the readout's ratedPlacementAt now goes through it.
• ratingShifts reports whether each building was rated up or down.
• gameStatuses (in data/placements.ts) classifies each building the way the game does. Tile pads, the pulse and the readout counts keep using the existing three-way PlacementStatus.
• PixiCanvas computes the overlays and the painter only draws them, in their own layer so a taller neighbour can't hide them.

Also contains a separate commit with the 1.1.11 re-extract of the cooler7/cooler8 art.

Testing

• npm run check and npm run knip are clean; all tests pass, including new ones for gameStatuses, ratingShifts, placementFillPercent and the icon mapping.
• Checked in the browser on a Singularity board, a Tidal board, and a hand-built board containing each state.
• Not yet tried by hand: flipping the Settings switch, and the 10% wasting-heat threshold against the real game (the threshold is from observed play, not read from the game files).
