Settings crashed with a TypeError: the profile card passed a SepotFingerprint object where the localized string formatter expects a String (hidden behind a `dynamic` parameter). Also fixes RangeError in avatar initials (empty names, double spaces) and switches initials to grapheme clusters so emoji don't get split. New photo preview screen: a captured or picked photo no longer sends immediately — it opens in a preview with freehand drawing (7 colours, undo), draggable text overlay, 90° rotation and a caption field. Nothing leaves the device until Send is tapped. Incoming-content hardening: decryption and content processing are now separated in the delivery path. Once an envelope is decrypted the ratchet has advanced, so redelivery can never help — permanently malformed content (FormatException/TypeError) is acked and dropped instead of poisoning the queue on every reconnect. Attachment metadata now validates base64 of the crypto fields up front, and a corrupt inline thumbnail no longer breaks bubble rendering. PNG without real transparency (screenshots, edited photos) is now re-encoded as JPEG — several times smaller on the wire. Tests: 116 (new widget tests for Settings and the photo preview, AttachmentMeta wire validation).
