Adds a sortable battles list as a new entity under the existing `view → table` submenu (entity slug `battles`), replacing the standalone top-level `battle log` shortcut which always opened a "battle not found" placeholder. The single-battle viewer stays put and is reached only by clicking a row (or a battle marker on the map), identical to the existing `section-battles.svelte` flow. Columns are planet (via the shared `planetLabel` helper) and shots (the per-battle action count carried by `BattleSummary`), sortable both ways with shots-desc default. No backend / FBS / map changes: the wire payload is unchanged. Participants / observers / total mass require the full BattleReport and were intentionally dropped to avoid N round trips per menu open. The top-level `battle log` item is removed from `header/view-menu` and `sidebar/bottom-tabs` (and their stale comment blocks updated); the now-orphan `game.view.battle` i18n key is dropped from both locales.
