Balanced ship tables and confirmed Havoc presets

What changed

Current Structures has balanced columns, larger icons, resource-by-resource costs and compact structure artwork. Narrow screens use cards.

Public Shipstats and the staff Stats Editor have compact fixed-width columns and a Pop dmg% field.

Cruisers and Battleships deal 0.1% of defender starting population per surviving ship by default. Percentages sum up to 100%; other ship classes remain blank. Older overrides migrate once.

Havoc replaces class totals with ten ship quantities mapped to the corresponding named ships in each race.

Confirm setup validates all requested racial ships before applying. Invalid or missing matches block the complete application without partial changes.

Each confirmation saves the full Havoc form. The latest five browser-local setups are available in a dropdown; the sixth replaces the oldest. Loading requires a fresh confirmation before application.

Race colours distinguish Helion, Velari, Nexari, Kryth and Auralis in the editor and the Havoc matrix.
