feat(reports): add dinosaur-themed monthly report titles

Replace generic 'Monthly Report: January 2026' titles with catchy,
alliterative dinosaur-themed titles like 'Jurassic January 2026'.

- Add monthlyTitles array with 12 themed names
- Update title format to use dinosaur themes
- Maintain deterministic /YYYY/MM slug format

Titles by month:
- January: Jurassic January
- February: Fossil February
- March: Mesozoic March
- April: Allosaurus April
- May: Megalosaurus May
- June: Juravenator June
- July: Jovial July
- August: Archaeopteryx August
- September: Stegosaurus September
- October: Ornithopod October
- November: Nodosaurus November
- December: Deinonychus December
