- ct/etherpad.sh + install/etherpad-install.sh: use ether/etherpad
(canonical name; ether/etherpad-lite still redirects but the new
name is preferred)
- install/etherpad-install.sh: switch dbType from dev-only "dirty"
to sqlite at /var/lib/etherpad/etherpad.db on first config seed;
matches the same default we land on across the snap, .deb, and
Home Assistant add-on packagings
- json/etherpad.json: refresh note to reflect the sqlite default
and document postgres/mysql as alternatives via dbType/dbSettings
