fix(upload): increase attachment size limit to 50mb (#144)

* fix(upload): increase attachment size limit to 50mb

Raises body limits in web proxy and desktop app. Adds client-side size checks and better 413 error handling.

* fix(client): auto-compress large images to avoid server body limits

Adds client-side compression for images >1MB. Resizes to max 2048px and converts large PNGs to JPEG. Adds detailed logging for debugging.

* chore: remove debug logs from client and proxy
