db-migrations-flyway-liquibase: fix dead Redgate/Liquibase doc links and back the lock-defaults claim with a real transcript

Browse Source 
Several documentation.red-gate.com and liquibase.com URLs added in the previous commit had
since moved (Redgate restructured its docs under /flyway/reference/, Liquibase Pro pricing
moved to /pricing); this repoints them at the current, verified-200 pages. Also captures
docs/output/16-liquibase-lock-defaults-javap.txt, the trimmed javap output backing chapter
11's claim about Liquibase's default lock-poll and lock-wait settings, which chapter 11
previously asserted without a committed artifact to back it.
