Add peekaboo DPM stat to Tankopedia firepower

Adds a **Peekaboo DPM** entry nested under DPM for single-shot guns, estimating damage per minute when only firing after resetting camouflage (or waiting out the reload, whichever is slower), assuming at least 10 seconds between shots.

- Shots per minute are capped at `60/10` for reloads faster than 10s, and fall back to `60/reload` otherwise
- The result is multiplied by the currently selected shell's damage and rounded
- An (i) icon next to the label opens a popover explaining the calculation
- The row is hidden for auto-loader/auto-reloader guns
- No percentile ranking bar is shown, since no dataset exists yet for this new stat
