fix(bootstrap): Run migrations with direct password before Vault is set up

The bootstrap order is vault -> tables -> directory. When tables
component was processed, it tried to call establish_pg_connection()
which requires Vault, but Vault setup only happens when processing
the vault component (which is earlier in the loop but the if-block
for tables runs for the tables component, not vault).

Fix: Run migrations directly with the generated password during the
tables component setup, before Vault is configured. This avoids the
dependency on Vault being set up.
