Fix three code-review findings from Discord notification refactor

- Add reference-equality cleanup guard to enqueuePickNotification so
  leagueChains entries are deleted once a league's chain settles (matching
  the old queue's finally-block cleanup), while correctly skipping deletion
  if a new pick was enqueued before the current one resolved
- Use getTeamForPick from ~/lib/draft-order in draft.make-pick.ts and
  draft.force-manual-pick.ts instead of the inline calculatePickInfo +
  draftSlots.find pattern (draft-utils.ts has a same-named local function
  with a different signature so it keeps the two-liner)
- Replace pickedTeam?.name ?? teamId UUID fallback in force-manual-pick
  with expectedDraftSlot.team.name, which is already validated non-null
  by the route's own guard; also removes two duplicate draftSlots.find
  calls that re-searched for a slot already in hand
