Reliably embed failure screenshots in Nextcloud Talk

Screenshots often fell back to "too large to embed" text instead of the
actual proof image. A single fixed 800px PNG encode exceeds Nextcloud
Talk's 32000-char message limit once base64-expanded (~74KB).

Encode as JPEG (much smaller for UI screenshots) and step the width down
through a list of candidates until the embedded message fits, keeping the
largest size that does. Typical search-failure screenshots now embed at
full 800px width; even a 336KB screenshot embeds at 520px.
