Replace the four-line text yield breakdown with five icon-based rows that draw
total production as icons and show surplus/loss as a signed group. Hovering any
row reveals exact figures and derived facts like growth/starvation timers.
Replace the comma-separated supported units list with wrapped unit chips that
show each unit individually, including veteran status (gold dot) and upkeep
color coding. Chips display a "+N" overflow marker when units exceed the
visible grid.
Extract citySupport() from cityYields() to compute per-unit upkeep in one pass,
ensuring the Shields/Gold rows and unit chips always agree on costs. Add
describeYieldRow() and describeSupportedUnitTooltip() tooltips for the new
visual elements. Add comprehensive headless tests covering icon run logic,
yield identities, government upkeep rules, and tooltip rendering.
