Localize hardcoded user-facing nameplate/bag/frame strings

Route the remaining hardcoded English labels through the T translation
table and register the keys in enUS:

- bags: "Sort Bags" / "Sort Bank" tooltips
- farmmode: "FARM MODE" overlay
- unitxp: "BEHIND" / "NO LOS" target indicators
- unitframes: raid group header "Group" (reuses the existing key)
- bgscore: "Battleground Frames" mover title
