[P1] Re-author the refMap service sprites at the 10x45 scale (they are resampled, not redrawn)

Found by the adversarial review on PR #811 (world scale moved to TILE 10 / FLOOR 45).

refMap in src/render/sprites/facilities/serviceKit.ts:15-39 documents its contract as: "At the canonical bake size (w === RW, h === RH) the map is the identity, so the port is pixel-exact."

Every caller authored its reference at the retired TILE 11 / FLOOR 44, so no caller can hit identity any more:

Every rect now ports through Math.round(rx * 10/11) horizontally and x 45/44 vertically. Concrete damage: the security monitor wall (service.ts:32-41, five monitors at reference pitch 10, width 8) lands at columns 5, 15, 24, 33, 42, a pitch of 10/9/9/9 with widths 8/7/7/7/7, so a regular 2x5 grid renders visibly irregular. wallp's 12px seam pitch becomes 11/11/10, box()'s 1px lit-left and shaded-right edges collapse into one column on roughly one position in eleven, and 45/44 inserts one duplicated pixel row into all six sprites.

Nothing tests this, which is why it was invisible.

Fix: re-author the six reference maps at the shipped scale, or make the reference size derive from TILE/FLOOR so identity holds by construction. Art work, so it goes through the room-design approval gate in the visual-parity GDD.

Also fix serviceKit.ts:6, which states "the canonical footprint (TILE 11 by FLOOR 44)" as fact.

Start with src/render/sprites/facilities/serviceKit.ts:6 and :15-39, then inspect the six callers listed in garage.ts and service.ts. Read the visual-parity GDD and room-design approval requirements before choosing whether to re-author the reference maps or derive their sizes from TILE/FLOOR. Done means the six sprites preserve identity at the shipped scale, the canonical-footprint wording is corrected, and visual approval is obtained.
