Route UI labels through the string table

Move start menu, settings, pause, Help, HUD, radio, shift review and campaign
labels/templates into content/strings.en.json, including placeholder-validated
dynamic status text. No player-facing hardcoded labels remain outside dynamic
data/debug output. Headless 250/250, docs check OK.
