* don't set emoji / media image paths on failed download, migrate FileType from string to integer * fix incorrect uses of util.PtrOr, fix returned frontend media * fix migration not setting arguments correctly in where clause * fix not providing default with not null column * whoops * ensure a default gets set for media attachment file type * remove the exclusive flag from writing files in disk storage * rename PtrOr -> PtrOrZero, and rename PtrValueOr -> PtrOrValue to match * slight wording changes * use singular / plural word forms (no parentheses), is better for screen readers * update testmodels with unknown media type to have unset file details, update attachment focus handling converting to frontend, update tests * store first instance in ffmpeg wasm pool, fill remaining with closed instances
