fix: validate emoji rune from utf8.DecodeRuneInString

Browse Source 
DecodeRuneInString returns utf8.RuneError for invalid UTF-8, which was
silently converted to the hex string "fffd" and sent to Confluence.
Return an error instead so the caller gets a clear diagnostic rather
than storing a replacement character as the page emoji.
