anti 12aa98a83c fix: migrate TEXT→MEDIUMTEXT for attacker/state columns on MySQL ...

Existing MySQL databases hit a DataError when the commands/fingerprints
JSON blobs exceed 64 KiB (TEXT limit). _BIG_TEXT emits MEDIUMTEXT only
at CREATE TABLE time; create_all() is a no-op on existing columns.

Add MySQLRepository._migrate_column_types() that queries
information_schema and issues ALTER TABLE … MODIFY COLUMN … MEDIUMTEXT
for the five affected columns (commands, fingerprints, services, deckies,
state.value) whenever they are still TEXT. Called from an overridden
initialize() after _migrate_attackers_table() and before create_all().

Add tests/test_mysql_migration.py covering: ALTER issued for TEXT columns,
no-op for already-MEDIUMTEXT, idempotency, DEFAULT clause correctness,
and initialize() call order.
