* add table who's rows each represent the lowest published btc block that an l2_keystone is found in * on bfg startup, backfill existing l2_keystones' lowest btc block * use pop_basis database notifications to continue to index these l2_keyston <-> lowest btc block * update finality queries to use this * allowing insertion of l2_keystone abreviated fields, as we sometimes will pull these from the btc chain and they are abbreviated there * add tests

Summary
simpler finality calculations with new table
Changes
more context:
this pr adds a database table
l2_keystones_lowest_btc_block
, which asl2_keystone_abrev_hash
as a primary key. this represents, for each distinct l2 keystone, the published lowest btc block this l2 keystone was found in. this way, we no longer have to calculate this at query time.
