Data: nightclub warehouse capacity with 2 to 4 floors #35

gta.wiki (Nightclubs/Warehouse Management) gives goods capacity for 1 and 5 warehouse floors only (e.g. Cargo and Shipments 10 / 50). For 2 to 4 floors LSOS estimates that every floor holds as much as the first (Cargo: 20, 30, 40), marked "(est.)" in the UI (decisions 013, 015).

The same page also says "each subsequent floor doubles that storage capacity", which contradicts its own table, so it is not used.

Wanted: a source or an in-game check of the capacity per goods type with 2, 3 or 4 floors. If it matches, drop the estimate in capacity() (src/lib/nightclub.ts); if not, put the sourced values in src/data/nightclub.ts.
