Adjusts credit value to be more consistent (#20913)

- Reworked prices, wages and balances of (almost) everything ingame.
- Added coinage and decimal support to cash, ruthlessly sanitized to
avoid floating-point errors. Reflected in cash-related things like ATMs.
- Tweaked how cash bundles are made and distributed to support
decimalization.
- Adjusted the starting money individuals and departments receive in
their accounts.
- Adjusted the funding Tajara, Unathi, Diona, Vaurca, and IPCs receive
in their accounts. Should earn more on average than they used to.

Credit values are now roughly 1/10th what they were before, across the
board.

Coins were added too! These have names:
- Unie: 0.01 credits
- Quin: 0.05 credits
- Dece: 0.10 credits
- Quarter: 0.25 credits

These can be seen cameo'd in the screenshots below.

Values, wages, etc, are based on the wiki page
https://wiki.aurorastation.org/index.php?title=Guide_to_Wages_and_Pay .

Values are not anchored to any singular real-world currency.

Example price differences:

| Example Item | Old Price | New Price |
| --- | --- | --- |
| Comet Cola | 15.00 | 1.50 |
| Cup Ramen | 20.00 | 2.00 |
| Jyalara | 38.00 | 3.00 |
| Trans-Stellar Cigarettes | 76.00 | 9.00 |
| Zo'ra Soda | 29.00 | 2.50 |
| Gumball | 5.00 | 0.25 |
| 50x plasteel sheets | 700.00 | 120.00 |
| 5x meat (cargo) | 160.00 | 55.00 |
| 50x phoron crystals (cargo) | 2200.00 | 400.00 |

Wages and account balances have also been tweaked:
| Type | Old Amount | New Amount |
| --- | --- | --- |
| Ship Account | 75,000.00 | 35,000.00 |
| Departmental Accounts | 10,000.00 | 15,000.00 |
| Personal Account (avg) | 200.00 - 20,000.00 | 20.00 - 2,000.00 |

Might break the economy; prices will likely need some adjusting
depending on gameplay constraints. Can be adjusted in TMs.
A little testing never hurt anyone.
