feat(ui): Phase 29 map visibility toggles

Adds the gear-icon popover on the map view with per-game persistence
of every category toggle plus the wrap-mode radio. Hide-by-id and
visibility-fog facilities land on the renderer so every flip applies
within one frame without a Pixi remount; the wrap-mode toggle keeps
its existing remount + camera-preserve path. A new server-side turn
force-resets every flag to defaults so a hidden category never makes
the player miss the next turn's news.

Also fixes the FligthDistance → FlightDistance typo in pkg/calc/race.go
(plus the single Go caller); the TS side keeps duplicating the formula
until a race-level WASM bridge lands.
