feat(browse): Cancel button on the identity-rename cue

Browse source 
Adds a Cancel button alongside "Rename file & reopen" that discards the manual
identity-field edits and restores the filename-derived values (leaving the rest
of the front matter + body untouched), then recomputes dirty + the cue.
