fix(i18n): correct Spanish large number translations to use long scale

Spanish uses the long scale numbering system, where 'billón' means
10^12 (not 10^9 as in English). The previous translations were direct
phonetic mappings from English short scale names, which are incorrect
for Spanish speakers.

Correct mappings (English short scale → Spanish long scale):
- billion  (10^9)  → mil millones / miles de millones
- trillion (10^12) → billón / billones
- quadrillion (10^15) → mil billones / miles de billones
- quintillion (10^18) → trillón / trillones
- sextillion (10^21) → mil trillones / miles de trillones
- septillion (10^24) → cuatrillón / cuatrillones
- octillion (10^27) → mil cuatrillones / miles de cuatrillones
- nonillion (10^30) → quintillón / quintillones
- decillion (10^33) → mil quintillones / miles de quintillones

Fixes #101
