Route the full-screen and group-event edit actions by the walk's unique id (editIdentifierFor) instead of the slug, so two walks that share a slug no longer open the same record when edited.
Compare the website title against the Ramblers title using walkTitle() (which applies replaceSpecialCharacters) instead of the raw title, so titles cleaned on upload (& -> and, apostrophes removed) no longer get flagged as needing republishing when they are already correct on Ramblers.
Fix walkTitle() calling replaceSpecialCharacters as an unbound map callback, which threw on possessive/contraction titles (e.g. "St Margaret's") at upload, during validation and on the publish page.
Add unit tests covering the title transform and the publish-status title comparison, including a regression guard for genuine differences.
