feat(bangs): add bang counter dashboard widget

Adds a new "bangs" module with a dashboard widget that tracks household
bang events. The widget shows the total count, a configurable recent-bang
list, and an "Add Bang" button that accepts a backdatable date.

On submission, a full celebration sequence fires: screen flash, widget
shake, count pop animation, synthesized firework sound (Web Audio API),
50 full-screen emoji particles via portal, canvas-confetti star bursts,
side cannons, and a timed sequence of 7 firework bursts.

- New bang_events table (migration 0017)
- canvas-confetti dependency for fireworks/confetti effects
- CSS keyframe animations: shake, countPop, emojiFloat
- Fixes pre-existing Drizzle snapshot chain collision (0007/0008)
- Adds OpenPlantBook env vars to compose.yaml
