channels: replace Member's six parallel prefix bools (oprefix/owner/admin/op/halfop/voice) with a single u8 bitfield (PFX_*) + inline bool accessors/mutators — same semantics, one byte instead of six, no more risk of the flags drifting out of sync; all call sites go through op()/set_op()-style methods
