[PWGDQ] Fix FIT detector accessor method names in BC-based FillFIT

- Changed has_foundFT0() -> has_ft0(), foundFT0() -> ft0()
- Changed has_foundFV0() -> has_fv0a(), foundFV0() -> fv0a()
- Changed has_foundFDD() -> has_fdd(), foundFDD() -> fdd()
- Matches standard O2 BC table accessor naming convention
