fix(wiki): address PR #107 review — catalog.md sync, math fix, schema fix

- catalog.md: sync star types for GJ 875 (K), GJ 1111 (M), GJ 541 (K),
  GJ 601A (F), GJ 19 (G), GJ 42 (K); add Dois Sóis name for GJ 707
- GJ-1111: fix calibration note total ~1.46M → ~1.67M, station display
  1M → 1.2M to match proposal
- GJ42 proposal: moon GJ42e-2 biome_summary ice → frozen (schema fix)
- GJ3943 proposal: station notes k-m → K5V+M3V
- GJ-3943 wiki: "five corridor communities" → "four" (Eerste Wacht
  joined later)
