feat(members): assign team roles from the tournament registration sheet

Match members by Discord username against the lineup nicknames in the
separate registration spreadsheet (TEAM_SHEET_ID) and give each their
team's role. One team per person: switching teams removes the old team
role, and a team with no Discord role yet is auto-created. Only role
names present in the sheet are ever touched, so organisation/field/base
roles are never at risk; the feature is a no-op when TEAM_SHEET_ID is
unset.

The sheet is not a single table (merged rows, stacked CS2/LoL sections
with different layouts), so it is parsed via raw-row scanning rather than
get_all_records. Citizenship markers like "(EST)" are used only as
player delimiters and discarded.
