"""Bring an existing database's membership tiers in line with the six plans
on tncsc.com/membership-registration.

data/membership_data.xml is noupdate="1", so an upgrade creates the new
tiers (Long-Term, Senior Life Term) but leaves existing ones untouched.
This script rewrites those, and archives the old "Individual" tier, which
TNCSC doesn't offer. Archiving, not deleting, keeps it on any member
already holding it.
