fix: make $applyConstraintToLastRoute public and remove unreliable method-indexed route scan

- Change $applyConstraintToLastRoute from private to public in matching.cfc
  so Lucee 7's mixin system can resolve calls from public constraint helpers
  (whereNumber, whereAlpha, etc.)
- Remove Fast Path 2 (method-indexed route scan) from Dispatch.cfc which
  returned stale wildcard routes instead of correct specific routes. Keep
  Fast Path 1 (static O(1) lookup) and the linear fallback scan.
