fix(etl): add missing table insertions

[shprink]

Description

ETL PostgreSQL

the write_data() function only generated INSERT INTO vehicles but never generated inserts for the child tables, even though the data was available on the Vehicle struct.

What changed:

After each vehicle INSERT, the ETL now generates INSERT statements for:

• charge_ports — from vehicle.charge_ports (1,275 rows)
• range_ratings — from vehicle.range.rated (1,590 rows)
• sources — from vehicle.sources (1,406 rows)
