Show rebirth level on Rebirth tab of City hall officer

A small QoL addition. Checking the Rebirth tab on the City Hall Officer should show the level of your rebirth before paying the 50k (and mess up your bag to deposit gear). For example, below the "Requirement : 50,000 Gold" there could be a "Progression : Level 32+16", and if you haven't started it could simply show Level 1+16. At 140+20, it could show Maximum Level Reached or 140+20.
