Implements REQ-UI-ITEM-ICON and REQ-UI-RECIPE-ICON. Adds an optional
recipes.toml `icon` field (an item id; defaults to the recipe's first
output). New ItemIconCache loads per-item SVGs from icons/items and
caches pixmaps per target pixel size, shared by:
- the Miner/Assembler recipe-selection dialog, which now shows icon-only
option buttons (name-caption fallback when no icon file exists), and
- GameWorldView belt/port item rendering via a shared drawWorldItem
helper (colored-square fallback preserved).
Shipyard schematic dialog is unchanged. No icon art is shipped; every
path falls back cleanly when an item has no SVG.

Lift unlocking into first-class unlock groups defined in unlocks.toml, so
one defence-station drop can grant a bundle of ships/modules/buildings/
recipes at once (e.g. the salvager module + salvage bay), and buildings
can now be locked at game start and unlocked via a drop.
Config:
- New UnlocksConfig + ConfigLoader::loadUnlocks + validateUnlocks (unknown/
duplicate/non-assembler grants, unknown requires, empty group all fail load).
- Drop unlock_at_station_level/unlock_requires from ship/module/recipe defs;
add unlocked_at_start bool to recipes for graph-unreachable base recipes.
Simulation:
- Track awarded groups + per-building unlock state; an item starts unlocked
iff no group grants it. Rework generateSchematicChoices/applySchematicChoice
to operate on groups (grant all members at once). Extend state checksum.
- isBuildingUnlocked query; tryPlaceBuilding rejects locked types.
UI:
- Build-menu buttons for locked buildings start hidden, revealed via a new
UnlockedBuildingsChangedEvent (emitted from GameWorldView's poll loop).
- Schematic choice dialog lists a group's granted items.
- Blueprint placement excludes locked building types (REQ-LOCK-UI-BLUEPRINT).
Data: unlocks.toml (app + test) reproduces the prior per-item gates as
singleton groups and adds salvage_operations (salvager + salvage_bay, lvl 1)
and reprocessing (reprocessing_plant, lvl 2).
Tests: rewrote unlock/config/recipe-schematic/artifact/wave/shipyard tests
for the group model; added UnlockGroupTest. All 443 cases pass.
