feat: profile page character display, persistent auth, cleanup

- Large animated sprite on BotProfilePage with tier-aware rendering
- Dynamic status titles (UNSTOPPABLE, ON FIRE, FRESH MEAT, etc.)
- Nostr auth persisted to localStorage — survives navigation and HMR
- Remove grotesque close-up overlays (eyeballs, tongues, teeth, drool)
- Remove crowd cheering signs (too small to look good)
- Add archetype to bot stats API response
- SpritePreview now accepts tier prop
