fix: robust coaster matching + dark carnival color scheme

Matching fixes:
- normalize() now strips all non-word/non-space chars via [^\w\s] instead of
  a hand-rolled list, catching !, curly apostrophe (U+2019), and any future edge cases
- Add isCoaster() helper with prefix matching (min 5 chars) to handle subtitle
  mismatches in either direction (e.g. "Apocalypse" vs "Apocalypse the Ride",
  "The New Revolution - Classic" vs "New Revolution")
- Fix top-level rides loop which still used coasterNames.has(normalize()) instead
  of isCoaster() — this was the recurring bug causing top-level rides to miss

UI:
- Dark neutral base (#111) replacing cold navy and muddy purple
- Neon accent palette: hot pink, electric green, vivid yellow, cyan
- Park page max-width 960→1280px, calendar cells 72→96px tall
- Scrollbar accent matches theme
