KeyRoulette

# KeyRoulette 4.1

## Bug fixes
- Cross-realm keys are now shown correctly. Keys from party members on a
  different realm were received but never matched to their card ("no key
  found"). All names are now normalized consistently; existing saved data is
  migrated on load.

## Improvements
- Active key request: opening the window now asks other KeyRoulette users
  directly for their keystone instead of relying only on other addons.
- Diagnostics: /kr debug, /kr status, /kr sync (off by default).

## Since 4.0
- Spin animation (~2.5s spotlight landing on the winner, pop + glow).
- Roll modes & settings panel: Random / Favor low keys, No-repeat, Level range.
- More languages: French, Spanish, Russian (plus German/English).
- Updated for client 12.1; Mythic+ dungeons detected automatically each season.
