fix: ratings reliability + ratingstop/ratingbottom board commands

- generateratings: MemberCachePolicy.ALL + ChunkingFilter.ALL + guild.loadMembers()
  (JDA cached only 2 members on small guilds by default)
- RatingService: new Random(seed) per call instead of shared Random.setSeed (race)
- LogEmbeds ban/kick: null reason -> 'Не указана'
- RatingsRepository.getTopRatings/getBottomRatings (ORDER BY value, LIMIT)
- RatingBoardCommand: ratingstop/ratingbottom, top-3 medals, guild-scoped
