fix(discord): resolve user ID from DM interactions for approval clicks

Discord puts the clicking user at interaction.member.user for guild
interactions but interaction.user for DM interactions. The Gateway
handler only checked interaction.member, so DM button clicks resolved
to an empty user ID and were silently rejected as unauthorized.
