Query refactoring

[lolgame99]

• Split Existing GET Endpoint into 2 seperate Endpoints:
  • GetPlayOffersByClubId
  • GetPlayOffersByParticipantId --> Gets PlayOffers where given MemberId is either creator or opponent
• Added GET Endpoint to search playoffers by creator name
  • Searches Member by likeness on first and last name
  • Expects query param to have format of <firstName> <lastName>, <firstName>, or <lastName>,
• Added DTOs for entities containing nested DTOs
• Refactored all GET Endpoints to return PlayOfferDTO(s)
  • Return value contains all information regarding to playoffer --> club, member, reservation and court details
