docs: fix broken intra-doc links

- decrypt.rs: three refs to the #[cfg(test)]-only decrypt_sectors_mapped
  wrapper can't resolve in a non-test doc build; de-link to inline code
  (keeps the name, no broken link).
- Fix DecryptingSectorSource::with_content_ranges link to its full
  crate::sector path so it resolves.
