Subject: [PATCH] Fix multipart upload failure: raise body limit and fix catch
 syntax
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Axum 0.7 defaults to a 2 MB body limit, which rejects typical phone photos
(often 5–15 MB). Added DefaultBodyLimit::max(50 MB) to accept large images.

Also changed `catch {}` to `catch (e) {}` in the sessionStorage IIFE; the
optional-catch-binding syntax (ES2019) is not supported by all mobile
WebViews, which would have prevented the script from loading entirely.
