The Manager previously called setupBoth() on every test step, which
dropped both PostgreSQL and MariaDB tables and re-imported the full
DBLP TSVs (~9 reloads across 2 DBs in a single run, even though only
PostgreSQL was used). Now data is loaded once via load_data_postgres()
and only the indexes are swapped between tests via apply_indexes_postgres().
A reset_postgres(config, reload_data=False) helper lets callers force
a full reload when needed -- used after 'cl-both' tests, since CLUSTER
physically reorders the table and dropping the index alone does not
restore the original layout.
Also fixes two bugs found while reading the code:
- baseStrategy.run iterated 'self.queries' instead of '.items()',
which would crash on the first unpack.
- main.py was missing an execute() call after the Aufgabe 3 'cl-both'
setup, silently skipping that test.
