Seed the retention tests 50 rows per insert, not 500 (closes #198)

internal/database was the slowest test package, and three retention tests were nearly all of it. Most of their time went to seeding thousands of rows 500 per INSERT: the SQLite driver finds each parameter's value by scanning the statement's arguments from the first until it reaches that parameter's, so binding grows with the square of the parameter count, and a 500-row insert carries several thousand. Seeding 50 rows per insert stores the same rows. No test case or assertion changes. The header of script/test records the new figures; its 90s timeout stays.
