Join: let chosen positions default to direct placement

The moving link is team-first by design: it routes a new join to whoever needs
directs next, so the position whose link was actually clicked earns no entry
reward. Measured on #21 that came to 80 joins in seven days and zero entry
rewards, while the traffic paying for those joins was the owner's.

For a position being deliberately built out, that default is backwards. Any ID
listed in the new directDefaultIds config now behaves as ?direct=1 on its own
/join/<id> link - including every promo tool, flyer QR and downline-builder
entry that resolves through it - without needing the parameter appended.

?direct=0 still forces rotation for a single share, so the team-first behaviour
stays available rather than being replaced.

Config rather than hard-coded, and editable from the admin settings form, so
which positions get this can change without a deploy.
