Expand withdrawn currency list with Wikipedia's full historical table

Pulled the complete "Historical currency codes" table from
https://en.wikipedia.org/wiki/ISO_4217#Historical_codes and added
every code not already covered — ~85 more entries (Argentine austral,
Brazilian cruzeiro/cruzado through its several redenominations,
Yugoslav dinar variants, Bulgarian lev's earlier revisions, settlement/
funds-only codes like XEU/XFO/XFU/XRE, and more).

Cross-checked the full 127-entry list against the JVM's live-derived
"currently active" set to make sure nothing genuinely active got
added by mistake — clean, except for one deliberate exception:
Wikipedia lists "BGN" (a fourth, euro-replaced Bulgarian lev) as
historical, but the JVM still resolves BGN as Bulgaria's current
currency, so it's left out to stay consistent with what this app's
own JVM/Android path actually does — documented inline.
