Photo/video/audio/document uploads were hitting "context deadline exceeded" mid-flight on slow or mobile networks. Two layers capped the budget at 60s: - sendOverallTimeout (wraps the whole retry sequence) - http.Client.Timeout (caps a single HTTP request) Both are fine for text sends but too tight for multi-MB uploads (sketchnote images, PDFs, long voice clips). Split the retry budget by method: text sends keep 60s, media sends (sendPhoto/Video/Audio/Voice/Document) get a new sendMediaOverallTimeout of 3 min. Bump the shared http.Client.Timeout to 3 min so a single upload attempt can actually consume that budget — getUpdates long-poll is 25s, so the extra headroom doesn't affect polling. Closes #628
