Curation decisions

• FT protein-binding rows -> MODIFY to GO:0001223 transcription coactivator binding (FT = non-DNA-binding
  co-activator; matches FT review's GO:0003713 / GO:0140297).
• FDP row -> MODIFY to GO:0046982 protein heterodimerization activity, non-core.
• NEW GO:0001228 (activator, RNA pol II-specific) IDA from ChIP-seq/target activation.
• Photoperiodism IMP (PMID:9615462) kept as non-core: FD acts downstream of photoperiod perception.
