Add basic test of station initial power supply (#29698)

* Add basic test of station initial power supply * Add info about stored power vs needed amount * Update map list * Get it compiling again * Get it working again * Only run if explicitly requested * Fix merge * We call 'em batteries * Mark the test as dirty
