1.0.5: furnish every remaining interior

Extends the shape profile from ten tilesets to twenty-three -- 1,190
pinned tiles over ~130 maps -- surveyed against the standard the
finished interiors set: one 16px wall band carrying its built-ins,
half-cell counters, bookcase-collapsed shelving, thin-pool plant
standees, objects riding the furniture they are drawn above.

The recurring failures were rooms sunk into ponds by the three
stale-cache water ids (collision is per cell, so one trapped tile sank
its neighbours too), counters and cave edges towering to 32-48px,
racks fusing into deep monoliths, and anything in a walkable cell --
stools, tables, staircases, gravestone arches -- vanishing into the
floor.

Also fixes the door fold overwriting profile pins: it replaced the
resolved shape unconditionally, so stair pins on tiles their tileset
lists in doorTiles (Celadon Mansion, Pokemon Mansion 3F) silently did
nothing.
